| Question | Answer |
|---|---|
| Afferent | The transmission of neuronal impulse from the body toward the central nervous system |
| Autonomic | automatic or involuntary |
| Autonomic nervous system | division of the nervous system that controls the involuntary body functions |
| Axon | The part of a nerve cell that conducts impulses away from the cell body |
| Blood-brain barrier | A barrier that exist in the brain as a result of special permeability characteristics of the capillaries that supply brain cells |
| Brainstem | A section of the brain consisting of the medulla oblongata, pons, and midbrain : connect the cerebellum and forebrain to the spinal cord |
| Cell Body | The main part of a neuron from which axons and dendrites extend |
| Central Nervous System | Consist of the brain and spinal cord: acts to manage and coordinate motor and sensory control |
| Cerebellum | Structure located posterior to the pons and medulla oblongata: responsible for posture, balance, and voluntary muscle movement |
| Cerebrospinal Fluid | A fluid that fills the ventricles of the brain and also occupies spaces of the brain, spinal cord, and the arachnoid layer of the menings |
| Cervical | Pertaining to the neck region of the spinal cord: the region begins at the base and encumbers the first seven vertebra |
| Coccyx | The small triangular bone located at the base of the spinal column also known as the tail bone |
| Dendrite | The part of a neuron that branches out to bring impulses to the cell body |
| Efferent | The transmission of a neuronal impulse rom the central nervous system toward the body |
| Lumbar | The region of the spine that includes five vertebra in the area between the ribs and pelvis: also used to describe the area around the waist |
| Monoamine Oxidases(MOA) | Enzymes found in the nerve terminals, neurons, and liver cells: deactivate chemicals |
| Neuron | The functional unit of the central nervous system which includes the cell body, dendrite, axon, and terminals |
| Neurotransmitters | Chemicals that are transmitted form one neuron to another as electrical impulses |
| Parasympathetic Nervous System | Division of the autonomic nervous system in control to the feed or breed response |
| Peripheral Nervous System | Part the the nervous system outside of the brain and spinal cord |
| Sacrum | The large triangular bone at the base of the spine: helps form the pelvis |
| Somatic | The motor neurons of the peripheral nervous system that control voluntary actions of the skeletal muscles and provide sensory input |
| Sympathetic Nervous system | Division of the autonomic nervous system that functions during fight or flight |
| Thoracic | Pertaining to the thorax area or the chest essentially the region between the neck and abdomen |
