|
Term
|
Definition
| division of the nervous sys that controls the involuntary body functions; consists of sympathetic and parasympathetic divisions |
|
|
Term
|
Definition
| the part of a nerve cell that conducts impulses away from the cell body |
|
|
Term
|
Definition
| barrier that exists in the brain as a result of special permeability characteristics of the capillaries that supply brain cells; these prevent certain solutes or chemicals from being transferred from the blood to the brain |
|
|
Term
|
Definition
| a section of the brain consisting of the medulla oblongata, pons, and midbrain; they connect the forebrain and cerebrum to the spinal cord |
|
|
Term
|
Definition
| main part of a neuron from which axons and dendrites extend |
|
|
Term
|
Definition
| consists of the brain and spinal cord; acts to coordinate sensory and moter control of body functions |
|
|
Term
|
Definition
| Structure located posterior to the pons and medulla oblongata |
|
|
Term
|
Definition
| A fluid filling the ventricles of the brain and also occupies spaces of the brain or spinal cord and the arachnoid layer of the meninges |
|
|
Term
|
Definition
| Pertaining to the neck region of the spinal cord; the region begins at the base of the skull and consists of the first seven vertebrae |
|
|
Term
|
Definition
| the small triangular bone located at the base of the spinal column; also known as the tailbone |
|
|
Term
|
Definition
| part of a neuron that branches out to bring impulses to the cell body |
|
|
Term
|
Definition
| the transmission of a neuronal impulse from the central nervous system toward the body |
|
|
Term
|
Definition
| region of the spine that includes the five vertibrae in the area between the ribs (thoracic spine) and the pelvis (sacral spine); also used to describe the area of the back around the waist |
|
|
Term
| Monoamine oxidases (MAOs) |
|
Definition
| Enzymes (includes MAO-A and MAO-B) found in nerve terminals, neurons, and liver cells; they inactivate chemicals such as tyramine, catecholamines, serotonin, and certain medications |
|
|
Term
|
Definition
| the end portion of the neuron where nerve impulses cause chemicals to be released; these chemicals (called neurotransmitters) cross a small space (called the synaptic cleft) to carry the impulse to another neuron |
|
|
Term
|
Definition
| The functional unit of the nervous sys, which includes the cell body, dendrites, axon, and terminals |
|
|
Term
|
Definition
| Chemicals that are transmitted from one neuron to another as electrical nerve impulses |
|
|
Term
Parasympathetic
nervous sys |
|
Definition
| Division of the autonomic nervous sys that functions during restful situations; "breed or feed" part of the autonomic nervous system |
|
|
Term
| Peripheral nervous system |
|
Definition
| division of the nervous system outside the brain and spinal cord |
|
|
Term
|
Definition
| the large triangular bone at the base of the spine; it connects superiorly with the last vertebra of the lumbar spine and inferiorly with the coccyx (tailbone). It is wedged between the two hip bones and helps form the pelvis |
|
|
Term
|
Definition
| motor neurons of the peripheral nervous sys that control voluntary actions of the skeletal muscles and provide sensory input (touch, hearing, sight) |
|
|
Term
|
Definition
| division of the autonomic nervous sys that functions during stressful situations; "fight or flight" part of the autonomic nervous system |
|
|
Term
|
Definition
| the thorax area or the chest; aka region between neck & abdoment; region of spine that includes 12 vertebrae in the area between neck (cervial spine) and lumbar (lumbar spine) regions |
