1
Q

Anatomical variation

A

no affect on normal function. usually can’t tell there is a change unless you had a surgical procedure or imaging done

2
Q

Congenital anomaly AKA..

A

birth defect. Can be mild to severe.

3
Q

Expectations of anatomical variations

A

Students should realize that all bodies are unique, and there may be a change in where normal structure should be

4
Q

What the skin provides

A

Protection from the external environment. Containment (holds the body and its parts together). Thermal regulation. Sensation. Synthesis and storage of vitamin D

5
Q

Epidermis

A

Has a tough superficial layer, and a pigmented basal layer, which can also regenerate. NO blood vessels or lymphatic. Epidermis is nourished by the underlying dermis.

6
Q

Dermis

A

Elastic and collagen fibers make this layer. Feeds the epidermis. Collagen fiber patterns determine how the skin will wrinkle.

7
Q

Tension lines

A

Run longitudinally in the arms and legs, and runs transverse in neck and chest. In creases, it goes with the creased marks. Aging people wrinkle more because elasticity of skin decreases.

8
Q

Arrector muscles of hair

A

Cause hair on skin to stand up. causes goose bumps. in the deep layer of the dermis

9
Q

Subcutaneous

A

Between the superficial dermis and the deep fascia. Composed of connective tissues, sweat glands, blood, lymph and stored fat.

10
Q

Where is most of the body fat storage?

A

subcutaneous tissue

11
Q

Other functions of the subcutaneous layer

A

Cushioning, fat storage, and thermoregulation.

12
Q

Skin ligaments

A

extend through the subcutaneous layer and into the dermis. Where they are long and sparse, there is more mobility in the skin, like the back of the hand. Where they are dense, there is less movement, such as the palm of the hand. Rigidity there.

13
Q

Periosteum

A

bone covering

14
Q

Bursae

A

sacs that can have serous membranes in them that can fill with fluid. Normal when they are empty and don’t take up space. Problem when they fill.

15
Q

Partietal vs visceral layer

A

Parietal is adjacent to the body cavity wall. Visceral more internal?

16
Q

Axial Skeleton

A

head trunk and neck

17
Q

Appendicular

A

limbs and pelvic girdle.

18
Q

What do bones provide

A

support for the body and its vital cavities. Protection of vital structure
mechanical basis for movement. Storage for salts. Continuous supply of blood cells.

19
Q

long bones

A

tubular like the arms

20
Q

short bones

A

cuboidal (only in the ankle and wrist). tarsus and carpus

21
Q

flat bones

A

usually for protection like in the skull

22
Q

irregular bones

A

bones of the face

23
Q

sesamoid bones

A

knee cap. where tendons cross a bony joint.

24
Q

Synovial joints

A

has a fluid sac surrounding the joint, like the knee

25
Q

fibers joint

A

where fibers hold the joint together

26
Q

Syndesmosis

A

like the joint between the radius and the ulna. Also like the joint in the dent-alveolar syndesmosis of the teeth. theres a root that forms between the root of the tooth and the alveolar process of the jaw
