Brain

contains senory (afferent) and motor (efferent) neurons. transmits messages about sights, sounds, smells, tough, temp, etc. to the CNS.

regulates the glands and the muscles of the internal organs.controls things such as heartbeat, resperation, digestion.

the sympatheic and the parasympathetic

the branch of the AND that is most active during proceeses such as digestion that restore the body's reserves for energy (eg eating)

branch of ANS that is msot active during emotional responses sucha as fear and anxiety. spends the reserves of energy. remember: sympathetic is an emotion.

an unlearned response to a stimulus that may involve only two neurons--a sensory and a motor and even sometimes a third neuron called the interneuron

they transmit the neural impulse from the sensory neuron to the motor neuron

• grey matter--composed of nonmyelinated neurons.
• white matter--compused of budles of longer myelinated neurons.

• 1. leasioning
• 2.EEG--detects minutes amount of electricity in the brain.
• 3. CAT--xray beams that reflect an image back into a picture from many angles.
• 4.MRI-magnetic fields that cause parts of the brain to emit signals. records changes in blood flow to detect activity.
• 4. PET scan

oblong region of the hind brain thats involved with the regulation of heartbeat and respiration

bulge in the hindbrain that lies forward of the medulla. A bundle of nerves. transmits info about the body movement and is involved in functions related to attention sleep and a respiration.

part of the hindbran thats involved in muscle coordination and balance. (drunk tests examine this when police make you walk)

part of the brain that is involved in arousal, attention, and sleep. injury to this part of the brain often results in a coma

two egg shaped structures that serves as the relay station for sensory stimulation. carries info from nerve fibers below to the cerebral cortex above.

a bundle of nuclei below the thalamus involved in body temp, motivation, and emotion. (huger, thirst, agression) stimulation of hypothalamus causes animals to behave badly RAWR

group of structures involved in memory, motivation, and emotion that forms a fringe along the inner edge of the cerebellum. (50 first dates brain)

near the bottom of the limbic system. looks like 2 almonds. connected to agression. "rage response" when stimulated.

largest mass of the forebrain tht consists of the two hemispheres.

wrinkled surface ares (gray matter of the cerebrum). fissures=more surface area=more info stored

thick fiber bundle that connects the hemisphere of the cortex.

• 1. frontal lobe
• 2. parietal lobe
• 3. temporal lobe
• 4.occipital lobe

the section of the cortex in which sensory stimulation is projected.

section of the cerebral cortex that lies in the frontal love. nerual impulses in the motor cortex are linked to muscular responses throughout the body.

it retrieves visualm sensory, auditory memories and manipulates them into info that can be used to solve problems or think

language disorder in which the left hemisphere of the brain is damaged. sufferers have a hard time comprehending the meaning of language

a language disorder characterized by slow....uhhh...laborious...ehh..speech.
