Anatomical Terminology (Pg. 4)

Learn the terms: superior, inferior, anterior, posterior, medial, lateral, proximal, and distal.

Activity 1-Examining & Identifying Bones (Pg. 145)

Clavicle

Scapula: acromion, coracoid process, spine, suprascapular notch, glenoid cavity

be able to distinguish between right and left scapulae

* How does the shoulder girdle allow for such great mobility in your arms?

* Why is a dislocated shoulder such a common injury?

Humerus: head, greater tubercle, lesser tubercle, intertubercular sulcus, deltoid tuberosity, trochlea, capitulum, medial epicondyle (funny bone), coronoid fossa, radial fossa, olecranon fossa, distinguish between right and left humeri and the proximal and distal ends of the humerus

* What is the “funny bone”? What causes the tingling sensation when it is hit?

* What bones articulate with the trochlea and capitulum?

* What fits into the radial fossa, coronoid fossa, and olecranon fossa?

Radius: radial tuberosity, styloid process, head, proximal and distal end

Ulna: coronoid process, olecranon process, trochlear notch, styloid process, proximal and distal end

The Hand: metacarpals, phalanges, and the carpals

Activity 2 - Palpate the pectoral girdle and upper limb (Pg. 150)

Find the parts in listed in the book. Look at the figures and articulated skeleton for help

Bones of the Pelvic Girdle and Lower Limb (Pg. 151)

Pelvic Girdle: ilium, iliac crest, ischium, ischial tuberosity, ischial spine, lesser sciatic notch, greater sciatic notch, pubis, obturator foramen, pubic symphysis, pubic arch, acetabulum

* What is the adaptive explanation for why the acetabulum is so deep?

Activity 3 – Observing Pelvic Articulations (Pg. 152)

Be able to distinguish between male and female pelves

* How do male and female pelves differ?

* Why are male and female pelves different?

Leg Anatomy (Pg. 154)

Femur: fovea capitis, neck, head, greater trochanter, lesser trochanter, medial condyle, lateral condyle, patellar surface, proximal and distal ends, left and right.

* Where does a “broken hip” injury generally occur in the body?

Patella

Tibia: medial condyle, lateral condyle, tibial tuberosity, medial malleolus, anterior border, left and right, proximal and distal ends

Fibula: lateral malleolus, head, proximal and distal ends

* Does the fibula help support the body’s weight?

* If not, why is it so hard to walk with a fractured fibula?

The Foot: metatarsals, phalanges, tarsals

* What are fallen arches? What causes fallen arches?

Activity 5 – Palpate the pelvic girdle and lower limb (Pg. 156)

Find all of the parts listed in the book

Activity 6 – Constructing a Skeleton (Pg. 156)

Form a group of 3 or 4 and articulate all of the bones at your table into a skeleton.
