| A | B |
|---|
| ear drum | separates outer ear from middle ear |
| hammer, anvil, stirrup | bones in middle ear-transmit sound waves |
| cochlea | inner ear-snail shaped-detect sound |
| semi-circular canals | innner ear - used for balance and equillibrium |
| Eustachian tube | equalizes pressure between ear and atmosphere |
| cerebrum | thinking, intelligence, emotions |
| cerebellum | coordination |
| medulla oblongata | controls internal organs-heart rate, respiration etc |
| neuron | basic cell of the nervous system |
| autonomic nervous system | involuntary nervous system |
| sympathetic nervous system | controls "fight or flight" reaction |
| parasympathetic | controls body at rest |
| dendrite | receives nerve impulses from synapse |
| synapse | gap between neurons |
| neurotransmitter | chemical that carries nerve impulse over synapse |
| axon | long body of neuron |
| Myelin sheath | fatty insulation over axon |
| connects 2 cerebral hemispheres | corpus collasum |
| connects cerebrum to cerebellum | pons |
| regulates metabolism-found at base of brain | pituitary |
| cerebral region of the brain that receives visual info | occipital lobe |
| cerebral region of brain that receives sensory information | parietal lobe |
| cerebral region that processes emotions, judgement, reasoning | frontal lobe |
| cerebral region that receives auditory information and deals with memory | emporal lobe |
| brain and spinal cord | CNS |
| ll other nerves (other than brain and spinal cord) | PNS |
| auditory nerve | nerve from ear to brain |
| optic nerve | nerve from eye to brain |
| fovea | area of retina with most cones |
| blind spot | area on retina where optic nerve exits |
| problems with equilibrium located in this ear region | semi-circular canals |
| broken hairs in this cause loss of hearing | cochlea |
| regulates size of pupil | iris |
| opening in eye that lets light in | pupil |
| clear covering over the eye | cornea |
| bends the light-when cloudy is a cataract | lens |
| rods | cells for dim light vision |
| cones | cells for color and sharp vision |
| outer ear that funnels sound | pinna |
