Afferent neurons, or sensory neurons
Efferent neurons, or motor neurons
Central nervous system- brain and spinal cord Peripheral nervous system- - all other nerves
Somatic nervous system- controls voluntary movements
Autonomic nervous system- controls involuntary movements
Sympathetic nervous system- speeds things up- prepares body for fight or flight
Parasympathetic nervous system-- brings the body back to normal
Cerebral cortex- covers the lower brain and controls mental processes such as thought
Frontal lobes-– contains the motor strip and frontal association area Frontal association area – plays an important part in integrating personality and in forming complex thoughts Motor strip- band running down the side of the frontal lobe that controls all bodily movements
Parietal lobes -– area that contains the sensory strip Sensory strip- band running down the side of he parietal lobe that registers and provides all sensation
Occipital lobes- area that interprets visual information
Hemispheres- one-half of the two halves of the brain; controls the opposite side of the body
Corpus callosum - bundle of nerve fibers that transfers info. From one hemisphere to the other
Fissure- a lengthy depression marking off an area of the brain
Reticular activating system- the alertness control center of the brain that regulates the activity level of the body Split-brain
Endocrine system – system of all the glands and their chemical messages taken together Hormones – chemical regulators that control bodily processes such as emotional responses, growth, and sexuality Pituitary gland – the master gland of the body that activates other glands and controls the growth hormone
Growth hormone – hormone that regulates the growth process
Thyroid gland – controls and regulates the speed of bodily processes called metabolism
Metabolism – the speed at which the body operates of the speed at which it uses up energy
Adrenal glands – glands that release the hormone that causes excitement in order to prepare the body for an emergency
Adrenaline – chemical that prepares the body for emergency activity by increasing blood pressure, breathing rate, and energy level

13. When brain researchers refer to brain plasticity , they are talking about
the brain’s ability to regrow damaged neurons.
The surface texture and appearance caused by the layer known as the cerebral cortex.
The brain’s versatility caused by the millions of different neural connections.
Our adaptability to different problems ranging from survival needs to abstract reasoning.
New connections forming in the brain to take over for damaged sections.
