AIIMS NOVEMBER 2016

1. Ans. (c) Sulcus terminalis

Ref: Gray’s 41st ed page 511, Moore - Clinically oriented Anatomy 7th edition page 940The dorsum (posterosuperior surface) is generally convex in all directions at rest. It is divided by a V-shaped sulcus terminalis into an anterior, oral (presulcal) part that faces upwards, and a posterior, pharyngeal (postsulcal) part that faces posteriorly.

Anatomy of Tongue

Parts Root, Tip, and Body, which has (a) a curved upper surface or dorsum, and (b) an inferior surface.

Dorsum The dorsum is divided into oral and pharyngeal parts. The inferior surface is confined to the oral part only. The dorsum of the tongue is convex in all directions. It is divided into:

• An oral part or anterior two-thirds • A pharyngeal part or posterior one-third, by a faint V-shaped groove, the sulcus terminalis. The two limbs

of the ‘V meet at a median pit, named the foramen caecum. They run laterally and forwards up to the palatoglossal arches. The foramen caecum represents the site from which the thyroid diverticulum grows down in the embryo.

Root The root is attached to the mandible and soft palate above, and to the hyoid bone below. Because of these attachments we are not able to swallow the tongue itself. In between the two bones, it is related to the geniohyoid and mylohyoid muscles.

Tip The tip of the tongue forms the anterior free end which, at rest, lies behind the upper incisor teeth.

Papillae of the Tongue

These are projections of mucous membrane or corium which give the anterior two-thirds of the tongue its characteristic roughness. These are of the following three types.

Vallate or circumvallate papillae

They are large in size 1–2 mm in diameter and are 8–12 in number. They are situated immediately in front of the sulcus terminalis.

Fungiform papillae

The fungiform papillae are numerous near the tip and margins of the tongue, but some of them are also scattered over the dorsum

Filiform papillae The filiform papillae or conical papillae cover the presulcal area of the dorsum of the tongue, and give it a characteristic velvety appearance. They are the smallest and most numerous of the lingual papillae. Each is pointed and covered with keratin; the apex is often split into filamentous processes

ANATOMY

Artery, Vein and Lymphatics of Tongue Arterial supply It is chiefly derived from the lingual artery, a branch of the external carotid artery. The root of the tongue is

also supplied by the tonsillar and ascending pharyngeal arteries

Venous drainage The arrangement of the vena comitantes veins of the tongue is variable. Two venae comitantes accompany the lingual artery, and one vena comitantes accompanies the hypoglossal nerve. The deep lingual vein is the largest and principal vein of the tongue. It is visible on the inferior surface of the tongue. It runs backwards and crosses the genioglossus and the hyoglossus below the hypoglossal nerve. These veins unite at the posterior border of the hyoglossus to form the lingual vein which ends either in the common facial vein or in the internal jugular vein.

Lymphatics • The tip of the tongue drains bilaterally to the submental nodes. • The right and left halves of the remaining part of the anterior two-thirds of the tongue drain unilaterally to

the submandibular nodes. • The posterior one-third of the tongue drains bilaterally to the juguloomohyoid nodes, these are known as

the lymph nodes of the tongue.

ANATOMY

ANATOMY • Answers with Explanations

ANATOMY

1. Ans. (c) C

Ref: Gray’s 41st ed page 618, 619

See table of Branchial Arches in ANATOMY AIIMS Nov 2012

The patient presents with DiGeorge syndrome caused due to defective development of 3rd and 4th pharyngeal pouches. But since thymus develops from 3rd pharyngeal pouch and there is absence of thymus in this patient, the better answer is 3rd pouch.

DiGeorge SyndromeA congenital disorder in which defective development of the 3rd and 4th pharyngeal pouches results in hypoplasia or aplasia of the thymus and parathyroid glands.

2. Ans. (a) A

Ref: Grays 41st ed page 756, Langman’s Embryology 10th ed page 140, 352 The notochord expands between the developing vertebrae as localized aggregates of cells and matrix that form the nucleus pulposus of the intervertebral disc

Plate LegendsA = Notochord B = Amniotic cavity C = Ectoderm D = Mesoderm

Nucleus pulposus is central gelatinous portion of an inter-vertebral disc derived from proliferation of notochord cells. Mesenchymal cells between cephalic and caudal parts of the original sclerotome segment do not proliferate but fill the space between two precartilaginous vertebral bodies. In this way, they contribute to formation of the intervertebral disc. Although the notochord regresses entirely in the region of the vertebral bodies, it persists and enlarges in the region of the intervertebral disc. Here it contributes to the nucleus pulposus, which is later surrounded by circular fibers of the annulus fibrosus. Combined, these two structures, form the intervertebral disc.

4. Ans. (b) Deep nuclei of cerebellum

Ref: Grays 41st ed page 256, 335, Ganong 24th Ed, pg 249, Guyton 12th ed page 684

See HISTO PLATE 10 KEY

Note

A question on low power histology of cerebellum was asked in AIIMS Nov 2016.

Marked cells in the plate are Purkinje cells of cerebellum. Purkinje cell is inhibitory to deep cerebellar nuclei. The developed cerebellar cortex contains three layers: namely, the molecular layer, the Purkinje layer and the granular layer. Purkinje cell axons pass into the white matter and form inhibitory synaptic connections with neurons of the deep cerebellar nuclei, releasing GABA as the neurotransmitter. GABA is the main inhibitory transmitter and glutamate is the main excitatory transmitter of Purkinje cells.

Functional Unit of the Cerebellar Cortex—The Purkinje Cell and the Deep Nuclear Cell The cerebellum has about 30 million nearly identical functional units, one of which is shown in the figure. This functional unit centers on a single, very large Purkinje cell and on a corresponding deep nuclear cell. To the top and right in

figure, the three major layers of the cerebellar cortex are shown: the molecular layer, Purkinje cell layer, and granule cell layer. Beneath these cortical layers, in the center of the cerebellar mass, are the deep cerebellar nuclei that send output signals to other parts of the nervous system.

Neuronal Circuit of the Functional UnitThe output from the functional unit is from a deep nuclear cell. This cell is continually under both excitatory and inhibitory influences.

• Deep cerebellar nuclei: From lateral to medial, the four deep cerebellar nuclei are the Dentate, Emboliform, Globose, and Fastigial (Mnemonic: “Don’t Eat Greasy Food”). The globose and the emboliform nuclei are sometimes lumped together as the interpositus nucleus in lower species; the emboliform and globose nuclei may sometimes be referred to as the anterior and posterior interposed nuclei, respectively. The dentate nucleus, which is located most laterally and is by far the largest, is the only nucleus easily visible to the naked eye.

• The excitatory influences arise from direct connections with afferent fibers that enter the cerebellum from the brain or the periphery. Primary afferent inputs: The afferent inputs to the cerebellum are mainly of two types, one called the climbing fiber type and the other called the mossy fiber type. They send collaterals to the deep nuclei and pass to the cortex. The two main inputs to the cerebellar cortex are climbing fibers and mossy fibers.

A. Tracheotomy incision midway between sternal notch and cicoid cartilage over the 2-3 tracheal ring. Several types of incisions can be made on trachea, but most common are vertical or cruciate.

B. Tracheostomy stoma: Note the difference from the cricothyroidotomy stomy which is higher up than the tracheostomy stoma C. Cricothyroidotomy incision between the thyroid cartilage and cricoid cartilave over the cricothyroid membrane. Surgical cricothyroidotomy

provides a definitive airway (a cuffed tube in the trachea) if tracheal intubation is not possible. Technique for a surgical cricothyroidotomy is: � Using a scalpel, make a transverse skin incision, then carefully incise through the cricoid membrane � Enlarge the hole using artery forceps or the handle of the scalpel, rotate through 90° � Insert a size 6 cuffed tracheal or tracheostomy tube � Inflate the cuff, check the position and ventilate

A B

D. Cricothyroidotomy stoma: Note the difference between tracheostomy stoma which is lower down compated to cricothyroidotomy stoma. E. Percutaneous dilatational tracheostomy (PDT): PDT technique involves introduction of a guide wire into the trachea followed by

dilatation using a variable diameter single dilator (the Blue Rhino) and passage of the tracheostomy tube loaded over one of the three loading dilators. More specifically, the devices allow for two approaches to the dilation of the stoma:

1. Serial dilation (Ciaglia Percutaneous Tracheostomy Introducer Set): Ciaglia method developed in 1985 uses graded dialators. Serial dilation is achieved using numerous progressively larger dilators. Kit contains three soft loading dilators of varying outer diameters (OD), i.e. 21F (7 mm), 24F (8 mm) and 28F (9.3 mm). Cook Ciaglia percutaneous tracheostomy devices are sold sterile for single use

2. Single-stage dilation (Blue Rhino and Blue Rhino G2 Advanced Percutaneous Tracheostomy Introducer Set): Single-stage dilation is achieved wit a single rhino-horn-shaped dilator using an in-and-out motion.

Absolute contraindications Relative contraindications 1. Emergency tracheostomy 2. In pediatric (Children younger than 12 years)3. Midline neck mass 4. Non intubated patients 5. Unstable spine fracture

1. PEEP value > 20 2. Uncorrected coaculopathies 3. Infection near the intended site of tracheostomy 4. Difficult to palpate anatomical landmarks 5. Previous neck surgery distorting the anatomy

A Bakri Postpartum Balloon works on the principle of tampon-ade (for uterine atony) to stop bleeding. Success rate approximately 85 percent. Procedure: Insertion requires two or three team members. The first performs abdominal sonography during the procedure. The second places the deflated balloon into the uterus and stabilizes it. The third member instills fluid to inflate the balloon, rapidly infusing at least 150 mL followed by further instillation over a few minutes for a total of 300 to 500 mL to arrest hemorrhage.Advantage: There is continuous drainage hence the risk of infection is reduced.
