� Consists of neurons (nerve cells)

and neuroglial cells (1)

� Neurons are the functional cells

of nervous tissue (1)

� Locations: brain, spinal cord and

peripheral nerves (1)

� Functions: detect stimuli,

respond, and transmit

information to other cells (1)

� Key Features: few neurons with

cytoplasmic extensions and

multiple neuroglial cells (1)

(3)

� Found only in the heart

� Contractions provide the major force for moving

blood through the circulatory system. (1)

(1)

� Found in the walls of hollow

organs and tubes, the

internal muscles of the eye,

the walls of blood vessels,

and other areas. (1)

� Smooth muscle performs a

variety of functions,

including propelling urine

through the urinary tract,

mixing food in the stomach

and intestine, dilating and

constricting the pupils, and

regulating the flow of blood

through blood vessels.(1)

(1)

� With its associated connective tissue, constitutes about

40% of the body's weight and is responsible for

locomotion, facial expressions, posture, respiratory

movements, and many other body movements. (1)

� Function is to a large degree, is under voluntary, or

conscious, control by the nervous system. (1)

� Fat tissue

�Under the skin

� Functions: protection, insulation, support

and reserve food (3)

� Inner framework of spleen, lymph nodes,

bone marrow filtration

� Function: Support

� Tendons, ligaments, aponeuroses

� Flexible but strong connection

�Deep fascia, dermis, scars, capsule of the

kidney

� Connection support

� Skeleton

� Support, protection, calcium reservoir

• Alveoli of lungs:

absorption by diffusion of

respiratory gases

between alveolar air and

blood

• Lining of blood and

lymphatic

vessels(endothelium):

absorption by diffusion

filtration, and osmosis

• Surface layers of pleura,

pericardium, and

peritoneum(mesothelium)

: absorption by diffusion,

osmosis and also

secretion

• Surface of

mucous

membrane

lining mouth,

esophagus, and

vagina:

protection

• Surface of

skin(epidermis)

: protection

• Surface of

mucous

membrane

lining urinary

bladder and

ureters:

permits

stretching

• Surface of mucous membrane lining of stomach, intestines, and part of respiratory tract: protection; secretion; absorption; moving of mucus (by ciliated columnar epithelium)

• Lining of

portions of the

male urethra;

mucous

membrane

near

anus(rare):

protection ©3

• constitutes about 40% of the body's

weight responsible for:

• Locomotion

• facial expressions

• Posture

• respiratory movements

• Its function, to a large degree,

is under voluntary, or conscious,

control by the nervous system

Location: attached to bone

Function: initiation of body movement

and locomotion

Key Features: parallel cells with

striations and multiple nuclei placed

adjacent to the plasma membrane(1)

• found in:

• the walls of hollow organs and

tubes

• the internal muscles of the eye

• the walls of blood vessels

• variety of functions:

• propelling urine through the urinary

tract

• mixing food in the stomach and

intestine

• dilating and constricting the pupils

• regulating the flow of blood

through blood vessels.

Location: heart

Function: contraction of heart

Key Features: mononucleated cells;

striations; intercalated discs; branching(1)

found only in the heart, and its

contractions provide the major

force for moving blood through

the circulatory system

Locations: digestive, respiratory, urinary

tracts; blood vessels; uterus

Functions: movement of substances

through an organ; regulates vessel

diameter

Key Features: mononucleated cells; no

striations, no intercalated discs

(1)

Locations: brain, spinal cord and

peripheral nerves

Functions: detect stimuli, respond, and

transmit information to other cells

Key Features: few neurons with

cytoplasmic extensions and multiple

neuroglial cells

• functional cells of nervous tissue

• transmit electrical signals

• three principal parts:

• the soma

• Dendrites

• one axon or nerve fiber.

• The soma contains the nucleus.

Extending from the soma are

dendrites that receive information

and transmit it towards the soma

and one axon that transmits

information away from the soma.

(1)

Found in lining the

air passage of the

respiratory system

and certain

segments of the

male reproductive

system.

Pseudostratified

epithelia function in

secretion or

absorption.

(3)

Composed of one layer of cuboidal cells resting on a

basement membrane. Found in the ducts of organs,

such as the kidneys.

Ducts of sweat glands; covering portion of epiglottis

Fuction: Protection

Location: Glands

Function: Secretion

Between other tissues and organs

Function: Connection
