Helpful Tips for Learning Bones

Do NOT learn bones based on size!

EX: Just because a bone is big does not mean it is the femur!

For bone quizzes check out lecture CD-ROM(skeletal system chapter)

Anatomical Terminology, Pg.4

Superior = above Inferior = below

Anatomical Terminology, Pg.4

Anterior = front Posterior = back

Medial = toward the Middle Lateral = toward the side

Anatomical Terminology, Pg.4

Proximal = close to the trunk (Proximal ~ Proximity)

Distal = Distant from the trunk

Anatomical Terminology, Pg.4

Articulating the Skeleton

Ligaments connect bones together

Tendons join muscles to bone

What type of tissue are ligaments & tendons?

Spine

Scapula, Pg 147, Posterior View

Deltoid muscle attaches to the Spine

Humerus articulates at the Glenoid Cavity

Glenoid Cavity

Deltoid

Spine

Suprascapular Notch

Scapula, Pg 147, Anterior View

Suprascapularnotch allows fornerve passage

Distinguishing Left & Right Bones

1. Look at the bone’s morphology

2. Think of how it articulates with other bones

Humerus, Pg 148, Anterior View

Intertubercular Sulcus

Deltoid Tuberosity

Deltoid muscle attaches to the Deltoid Tuberosity

Bicep tendon passes through the Intertubular Sulcus

Deltoid

Bicep

Radius, Pg 149, Anterior View

Radial TuberosityBicep attaches at the Radial Tuberosity

Styloid ProcessWrist ligaments attach to the Styloid Process

Radial Tuberosity

Bicep

Styloid ProcessWrist ligament attachment site

Ulna, Pg 149, Lateral View

Distinguishing the Radius & UlnaRadius is on the thumb side of the forearm

The radius rotates when you twist your arm

Ulna has a wrench-like trochlear notch

Phalanges

Metacarpals

Carpals

Do Activity 1 and Activity 2

Find the answers to the questions in your handout

Illium

Ischium

Pubis

Pelvic Girdle, Pg 152, Lateral View

Greater Sciatic Notch

Lesser Sciatic Notch

G. & L. Sciatic Notchesallow for nerve andblood vessel passage

Pelvis, Pg. 152, Lateral View

Greater

Sciatic Nerve

Look at a Pelvis at your Table

Do Activity 3 – Pg. 152

Distinguish between male and female pelves

Femur, Pg 154, Posterior View

Greater Trochanter

Lesser Trochanter

Greater & Lesser Trochanters are attachment sites for buttock muscles

GreaterTrochanter

Patella, Pg. 154, Anterior View

The patella protects the knee joint

Tibia, Pg. 155, Anterior View

Tibial Tuberosity

Medial Malleolus

Attachment site for patellar ligament & quadriceps muscles

Helps stabilize the ankle joint

TibialTuberosity

Fibula, Pg. 155, Anterior View

Lateral Malleolus

The lateral malleolus helps to stabilize the ankle joint

Distinguishing between the Tibia & Fibula

The Tibia is Tough The Fibula is Flimsy

Calcaneus

Attachment site for the Achilles (Calcaneal) tendon

Distinguishing the Carpals & Tarsals

The Carpals are in the hand where some people suffer from “Carpal Tunnel Syndrome”

The Tarsals are near the Toes

Do Activity 5 – Pg. 156

Do Activity 6 - Construct a Skeleton
