Exam 1

Question 1

Cheek cell

Answer 1

stained with methylene blue, nucleus, plasma membrane

Question 2

Fat (adipose) cell (tissue)

Answer 2

fat accumulates inside other cell comppnonents pushed out, nucleus on outside part

Question 3

Goblin cells

Answer 3

Inside lining of intestine, creates mucus that lubricates and protects the inside of the intestine.

Question 4

Pacinian corpuscle

Answer 4

Looks like onion when cute in have with layers of connective tissue that surround the touch sensitive nerve edges. (mechanoreceptors in skin and organs)

Question 5

Spinal Neuron

Answer 5

spinal (multipolar) motor neuron, nucleus has large nucleolus, cytoplasm has nissle substance

Question 6

Bronchus cell

Answer 6

Ciliated cells on free surface of bronchi, (motile) to cleanse debris and mucus from lining of bronchial tubes and tracheas

Question 7

Multipolar neuron

Answer 7

Motor neuron, has multiple dendrites and its axon

Question 8

Medullated Nerve

Answer 8

Covered by myelin that acts as insulator for the electrical signal to not jump from nerves or neurons. Has nodes of ranvier

Question 9

Skeletal Muscle

Answer 9

Voluntary muscle. Fibers (cells) in the SM have striations of dark and light bands of actin & myosin fibers are multinucleated. Damage to nerve causes paralysis

Question 10

Nucleus

Answer 10

containes chromosomes/enzyme machinary. For cell division as well as cell function.

Question 11

Cell (plasma) membrane

Answer 11

outer membrane, holds stuff together

Question 12

Nodes of ranvier

Answer 12

unmylinated area that helps make electrical signal faster

Question 13

Nucleolus

Answer 13

small dark stained structure in nucleus. site for production of ribosomes which make their way to the cytoplasm and participate in protein synthesis.

Question 14

lumen

Answer 14

large space inside an organ such as the intestine or stomach.

Question 15

actin & myosin

Answer 15

Contractile muscle protiens in filaments

Question 16

Ribosomes

Answer 16

large macromolecular structures formed of RNA and protein which serve as sites for protein synthesis.

Question 17

Epithelium

Answer 17

one of the four tissue types that is characterized by cells which line free surfaces of the body, such as the skin and lining of the gut.

Question 18

Rough endoplasmic reticulum

Answer 18

membrane sheets with ribosomes attached which spread throughout the cytoplasm of most body cells with a primary function of protein synthesis.
