| A | B |
|---|
| Hypothalamus | controls emotions |
| Occipital lobe | processes visual information |
| Rectical Formation | controls sleep and arousal attention |
| Cerebellum | controls involuntary movements |
| Parietal lobe | sensory information from the skin |
| Corpus collosum | connects left and right hemisphere |
| Medulla | controls involuntary functions |
| Temporal lobe | processes hearing |
| Thalamus | realy station |
| Frontal lobe | processes speaking and thinking |
| Amygdala | controls fear, anger, aggression |
| Hippocampus | memory function |
| EGG | brainwave test |
| pons | portion of brainstem that plays a role in sleep and arousal |
| Sensory area | processing info that sensory neurons pick up |
| Motor area | interprets info then sends the signal to other parts of the body |
| Association area | communication between sensory and motor areas |
| Neurotransmitters | chemical messages in the nervous system that transmits info by crossing the synapses from one neuron to another |
| Central Nervous System | two main sturctures are the brain and spinal chord |
| Peripheral Nervous System | eveything except the brain and spinal chord |
| Sematic | muscle control- body transfers info from sensory organs to nervous system |
| Autonomic | connects nervous system to organs and glands (blinking, breathing) |
| Sympathetic Branch | help respond to stress |
| Parasympathetic | helps restore the energy that was lost |
| Endocrine System | consists of ducktless glands, glands secrete hormones |
| Pituitary gland | regulates eniter endocrine system |
| Neurons | keep us alive, each differ in function and in location but are same structure |
| Sensory Neurons | neurons that get info from the senses and send signals from sense organs to spinal chord and then to the brain |
| Motor Neurons | interprets- relays message back through the brain to the spinal chord |
| Interneurons | bridge gap between the two neurons |
| Glial cells | support neurons- insulate and provide neutrions to neurons |
| Reflexes | automatic response to a sensory stimulus |
| Soma | cell body |
| Dendrites | receptors of messages from neurons |
| Axon | send messages to other neurons |
| Myelin sheath | layer of fatty cells that are tightly wrapped around axon to insulate and speed movements of electrical impulses |
| Neurons in action | no half way point--fires or not |
| Resting state | inactive |
| Action potential | electrical impulses surging through an axon |
| threshold | level of stimulation needed to trigger a neural impulse |
| All or none principle | cuts off other neurons,, only do one thing,, bite tongue,, forget what eating |
| Synapses | gap between neurons that roughly one millionth of an inch wide |
| Neurotransmitters | cause neurons to fire |
| ACh- acetylchlorine | most concentrated in parts of the brain that control motor behavior |
| Dopamine | controls involuntary movements--too much schitsophrenia--not enought parkinson |
| Endorphins | natural opiates that relieve pain |
| Brainstem | connects spinal chord- responsible of heart rate, respiration, body temperature |
| Limbic system | helps regulate emotion memory, motivation |
| Cerebral cortex | largely responsible for the higher order mental process |
