Lecture 1

Question 1

Median (mid-saggital) plane

Answer 1

Divides body in left and right halves.

Formed by Cranio-cadaul & anterior posterior axes

Question 2

Frontal (coronal) Plane

Answer 2

Front and back halves of body

Cranio-caudal & Left-right(transverse) axes

Question 3

Transverse (cross-section) plane

Answer 3

Top and bottom halves of body

Anterior-posterior & L-R axes

Question 4

Cranio-caudal (vertical) axis (CC)

Answer 4

Medial and lateral rotation

Question 5

Anterior-posterior (AP) axis

Answer 5

Abduction & adduction

Question 6

Left-right (transverse) axis

Answer 6

Flexion and extension

Question 7

Flexion & extension

Answer 7

Median (saggital) plane around LR/transverse axis

Question 8

Abduction & adduction

Answer 8

Frontal (sagittal) plane around AP axis

Question 9

Lateral and medial rotation

Answer 9

Transverse plane, cranio-caudal axis

Question 10

Where is thick skin found?

Answer 10

Only on the palms & soles of feet

No hair follicles
0.4-0.6 mm thick

Question 11

Where is thin skin found?

Where is the most thin skin?

Answer 11

Everywhere else (not palms or soles of feet)

Thinnest thin skin = eyelids
Thickest think skin = back

Question 12

Describe the dermis and its 2 layers

Answer 12

Deepest region - vascularized

2 Layers = Papillary (loose CT) & Reticular layer (dense irregular CT)

Question 13

Describe epidermis

Answer 13

Avascular, innervated, 4-5 layers

• Stratum corneum (cells are dead and keratinized)
• lucidum
• granulosum
• spinous
• basale

Question 14

Superficial fascia

Answer 14

Layer of CT the integument sits on

-loose bundles of collagen, elastic fibers with some adipocytes

Question 15

Deep fascia

Answer 15

Tightly adheres to muscles, bone, tendons

Several thin layers of collagen

Question 16

What method of secretion do sudoriferous (sweat glands) glands use?

Answer 16

Merocrine = thin, watery secretion—> no damage to the cell

Apocrine = top of cell is secreted along with the secretion - so the top part of the cell is lost
Labia majora

Question 17

What type of method secretion do sebaceous (oil) gland use?

Answer 17

Holocrine — whole secretory cell becomes lost as part of the secretion

Question 18

Are hair follicles innervated?

Answer 18

Yes

Question 19

Parts of the nail

Answer 19

• Ungis (avascular not innervated)
• Matrix
• Subungis (highly innervated)

Question 20

What is a dermatome?

Answer 20

Specific region of skin innervated by a specific spinal cord level
