Question 4

Nervous tissue

Answer 4

Carrying out impulse conduction

Question 5

flattened cells lining a body surface, one cell layer thick

Question 6

Simple Cuboidal E.

Answer 6

cells shaped like cubical boxes. one cell layer thick

Question 7

Simple Columnar E.

Answer 7

shaped like shoe boxes. one cell layer thick. help take up digested food products in small intestine like, amino acids, proteins and sugars

Question 8

Stratified squamous E.

Answer 8

Epithelium formed of many cell layers of flattened cells

Question 9

Epidermis

Answer 9

outer layer of skin, made by stratified squamous E. cells closest to free surface water proofed by high keratin

Question 10

Keratin

Answer 10

water proofing molecule produced by the outer cells of the epidermis

Question 11

Skeletal muscle fiber

Answer 11

Single muscle fiber that has multiple nuclei, striation and is volantary mode of contractile control

Question 12

Cardiac muscle fiber

Answer 12

In the heart and have only one nucleus per cell, striations, fiber branching, involuntary muscle

Question 13

Intercalated disks

Answer 13

only in heart muscle, dark stained areas indicating where two cardiac cells have adhered together end to end.

Question 14

Smooth muscle fiber

Answer 14

Do not show striations, one nucleus per cell

Question 15

Peristalisis

Answer 15

Movement of digested food through the intestine by a sequential contraction of layers of smooth muscle in the intestinal wall

Question 16

Nerve process

Answer 16

Dendrites or axons

Question 17

Axon

Answer 17

Carries signal away from neuron

Question 18

Dendrite

Answer 18

Carries signal towards Cell body

Question 19

Nerve cell body

Answer 19

where nucleus of neuron is

Question 20

Multipolar neuron

Answer 20

Spinal motor neuron that has multiple dendrites, sends signals to muscles to coordinate skeletal muscle contraction, axons can reach leg

Question 21

Elastic cartilage

Answer 21

Like in the ear, contains elastic fibers, allow ear to be bent yet go back to normal shape

Question 22

Reticular fibers

Answer 22

provide support and ability for aorta to expand with each heart contraction due to pressure of blood flowing into it but then when the heart relaxes, they help aorta contract back to normal shap helping to push blood foward while heart is no longer contracting

Question 23

Glomerulus

Answer 23

a tuft of capillaries in the kidney, serve as the filtering mechanism step to rid the body of waste material in the blood

Question 24

Hyaline cartilage

Answer 24

composed of chondrocytes, fibers, and a gel-like substance which is fairly flexible and forms the tracheal rings which keep the trachea open for air passage.

Question 25

Chondrocytes

Answer 25

cells found in cartilage after it is fully formed.

Question 26

Haversian system

Answer 26

Round like areas in compact bone, circular area surrounding a capillary in compact bone which contains many osteocytes (mature bone cells).

Question 27

Haversian Canal

Answer 27

The center of the Haversian system that containes blood capileries bringing blood to the osteocytes

Question 28

Areolar Connective Tissue

Answer 28

Form dermis, loose connective tissue that consist of cell fibers (collagen and elastic), ground substance that is gel like.
