Bio Quiz

Cerebllum

posture and balance

Cerebrum

control perosnality, intelligence, learning, perception, and emotion

Frontal

Association of thought, motor cortex, speech, motor association

Paritelal

sensory association, tatse, touch

Tmeporal

hearing, auditory, smell, interpretation or perception

occipital

vision and visula assoc

Brain stem

Pon and medulla-essential function include breathing, heartbeat, but also controls movement of eyes, face and mouth

Cerebral cortex

sensory, motor, association areas

thalamus

process information and relays it to the cerebrum

pituitary gland

produces numerous hormones that affect target tissue directly or stimulate other endocrine glands

corpus clossum

connects left and right hemisphere allowing for environment between them

Hypothalamus

homestatic control of most organs

medulla

regulates essential physiological process such as blood pressure, heatbeat and breathing

pons

conncet forbrain with medulla and cerebellum

Sensory deafness

occurs when transmission of nerve impulses fro cochlea to the brain is impaired, exposure to loud sounds, infection and drug toxicities.

Conduction deafness

reduced ability to jear, due to problems between the outside of the ear and the cochlea, cause by eternal ear problems or middle ear dmamge

chochlea

site of auditory transduction

Auditory transduction

converting sound waves into electrical signals

Rods

respond to black and white and in dim environments

cones

detecting color

Astigmatim

when the cornea or lens have an abnormal curvature or other irregularity. This will cause part of and object to be in focus while another part is out of focus

emmetropia

normal vision

Visual acuity

ability of the eye to focus light on the reina for sharp vision

presbyopia

lens become less flexible and can no longer thicken enough to focus on near object. “Old eyes”

Peripheral nervous system

made of sensory and motor neurons

neurons

specilized nerve cells that transmit signlas

Sensory neurons

carrys signal from PNS to CNS

Motor Neurons

Carrys signla from CNS to PNS

axon

conducts nerve impulses away form the cell body

dendrites

short, branched extension that transmit information toward cell

cell body

contains the nucleus, mitochondria that supply ATP, ribosomes that manufacture proteins and organelles

mylein sheath

composed if matty materials coat section of the axon, speeding nerve impulse conduction

vesicle

hold neurotransmitter molecules

reuptake

neurotransmitter is taken back into sending neuron

neurtransmitter

a chemical signal that takes form a sending cell to a receiving cell across the spaces
