1

causes of conduction deafness

malformation of outer ear, fluid in middle ear, buildup of earwax

2

causes of motion sickness

stimulation of semicircular canals during motion

3

Characteristics of light and vision

pupil dilates with less light, constricts with more, rods help with night/low light vision, cones with color distinction

4

Characteristics of articular cartilage

hyaline cartilage that covers the ends of long bones, protects, prevents friction

5

elastic cartilage

similar to hyaline, found in external ear and epiglottis

6

fibrocartilage

highly compressed with great tensile strength
contains collagen fibers
found in menisci of the knee and in intervertebral discs

7

homeostatic imbalance

illness

8

hyaline cartilage

support, flexibility, resilience
most abundant of skeletal cartilages
articular- covers ends of long bones
costal- connects the ribs to the sternum
respiratory- makes up larynx, reinforces air passages
nasal- supports the nose

9

characteristics of odorants

bind to transmembrane odorant receptors of olfactory hair membranes, binds G proteins

10

characteristics of various muscle cells

r

11

action potential

electrical impulses carried along the length of axons, always the same regardless of stimulus
the underlying functional

12

afferent nerves

sensory nerves

13

conjunctiva

thin, transparent mucous membrane

14

desmosomes

junction between cells..???????????

15

disaccharide

common table sugar

16

efferent nerves

motor nerves

17

endomysium

surrounds a group of muscle fibers

18

epimysium

covers an entire muscle

19

excitatory potential

EPSP- excitatory postsynaptic potentials
graded potentials that can initiate an action potential in an axon
use only chemically gated channels
Na+ and K+ flow in opposite directions at the same time
postsynaptic membranes do not generate action potentials

20

ganglia

group of cell bodies located outside the CNS

21

gap junction

communication joint between cells

22

generator potential

because of a graded potential that must be strong enough to stimulate an action potential

23

graded potential

short response, smaller the farther away from source

24

mixed nerves

carry autonomic and somatic impulses
four types
somatic afferent and somatic efferent
visceral afferent and visceral efferent

25

monosaccharide

simplest form of carbohydrates

26

motor nerves

efferent, cause motion, stimulate muscle ends

27

nerves

bundle of axons and their sheaths

28

nuclei (nervous)

Basal Nuclei
masses of gray matter found deep within the cortical white matter
functions(thought to be)
influence muscular activity
regulate attention and cognition
regulate the intensity of slow or stereotyped movements
inhibit antagonistic and unnecessary movement

29

nucleic acid

DNA- genetic code
RNA- interprets DNA
ATP- energy source

30

peroxisomes

membraneous sacs that contain oxidases and catalases(enzymes)
carry out metabolic activity
destroy hydrogen peroxide
detoxify harmful or toxic substances
neutralize dangerous free radicals
free radicals- highly reactive chemicals with unpaired electrons
kidneys, liver
