Cell/general anatomy

Question 1

Clinical anatomy

Answer 1

studies anatomical changes that occur during pathological illnesses

Question 2

Cross sectional anatomy

Answer 2

using radiographic techniques to study cross sections of body

Question 3

Sagittal plane

Answer 3

Cuts the body into left and right

Question 4

Frontal plane

Answer 4

cuts the body into front and back

Question 5

transverse plane

Answer 5

cuts the body into proximal and distal

Question 6

Proteins synthesized on rough E.R

Answer 6

Are going to be excreted or go to an integral membrane organelle

Question 7

Proteins in cytosol

Answer 7

either to mitochondria or peroxisomes

Question 8

microfilaments

Answer 8

Made of actin
- anchor membrane proteins
- movement with myosin

Question 9

intermediate filaments

Answer 9

Provide strength and keep organelle positions

Question 10

Thick filaments

Answer 10

myosin used for movement

Question 11

microtubules

Answer 11

Made of tubular proteins
-form cytoskeleton
-change shape of cell

Question 12

Gq mechanism

Answer 12

1.PLC activates and converts PIP2 to IP3 and DAG
2.IP3 stimulates Ca2+ release from ER
3.Ca2+ binds calmodulin and activates protein kinases
4.DAG activates protein kinase C

Question 13

4 primary tissues

Answer 13

-Epithelial
-Connective
-Muscle
-Nervous

Question 14

Epithelia features

Answer 14

-Avascular (no blood)
-Sheets that regenerate
-Cover external surfaces
-Polar (have basal and luminal ends)

Question 15

Basal lamina

Answer 15

Secreted by epithelial cells to hold and secure cells

Question 16

Reticular lamina

Answer 16

Secreted by connective tissue underneath epithelial cells to hold it in place

Question 17

Squamous epithelia

Answer 17

Thin and flat

Question 18

Cuboidal epithelia

Answer 18

Looks hexagonal, makes up ducts and tubes

Question 19

Columnar epithelia

Answer 19

Long and thin make up linings
-makes pseudo stratified columnar

Question 20

Glandular epithelia

Answer 20

like Serous (watery), Mucous or mixed glands

Question 21

Secretory sheet

Answer 21

simplest glandular epithelia like lining of stomach

Question 22

Tubular vs alveolar

Answer 22

alveolar have a bulb on the end of duct

Question 23

Eccrine secretion

Answer 23

Uses secretory vesicles and exocytosis (eg, saliva)

Question 24

Apocrine

Answer 24

Product is concentrated in part of the cell then that section is shed to release (eg mammary glands)

Question 25

Holocrine

Answer 25

entire cell breaks apart to release product (eg sebaceous [oil] glands)
