Elements the human body makes up 96%

1

Action potential

Transient polarization event that includes polarity reversal of sarcolemma (nerve cell membrane)

The start of an electrical current

2

Anterior chamber of eye

Between cornea and iris

3

Blind spot of eye

Region where the retina connects to optic nerve whee there are no rods or cones to receive images--optic disk

4

Connective tissue

Blood is the tissue

5

Cartilage tissue

Tough elastic material found between bones of spine and ends of long bones

Shock absorber and allows for flexibility

Found in nose, ear, larynx

6

Ear infection
Allergies
Hole in eardrum
Earwax
Swimmers ear

7

Characteristics of irregular bone

Complicated shapes for protection

Vertebrae protects spine

Hip bones protect internal organs

8

Characteristics of neuron

Body (soma), axon, dendrites

Long lived, amniotic, high metabolic rate

Use highest amount of energy in the body

9

Characteristics of plasma membrane PPLC

Fine layers of phospholipids

Protein, lipids, carbohydrates

10

Characteristics of reticular fibers

Branched collagenous fibers that form delicate networks

11

Characteristics of spongy bone

Honeycomb of trabeculae filled with yellow bone marrow

Yellow marrow is made of adipose tissue and is in long bones

12

Characteristics of trabecular bone

Filled with yellow marrow

Same as spongy bone

16

Sarcomere

Contractile unit of skeletal muscles

17

Cornea

Circular and transparent in front of cornea

Allows light rays into the eye

First place where light is bent and refracted

18

Astrocytes

Most abundant glial cell

Cling to neurons and their synaptic endings

Cover capillaries

Support neurons, anchor them

Control chemical environment

19

Bursae

Flattened shapes

Sacs lines with synovial membranes and containing synovial fluid

20

Ependymal cells

Thin membrane of glial cells lining the ventricles of brain and central canal of spinal cord

21

Fontanelle

Soft spot, allow cranium to expand

22

Foramina

Round opening in bone

Passageway for blood vessels, nerves, and other things

23

Ganglia

Parasympathetic cell bodies

Surround cell bodies

24

Ligaments

Connective tissue band

Help hold long bones together at a joint

25

Menisci

Crescent shaped fibrocartilage acting as a cushion

All synovial joints

Part of knee

26

Mitosis

Split cell and make another

Cell division

Division of nucleus
