Study Notes

Nervous System Vocabulary

Axon: A crucial substance that facilitates the transmission of nervous pulses from one neuron to another.
Meninges: Comprise three protective membranes encasing the brain and spinal cord, critical for safeguarding the central nervous system.
Embolism: A medical condition involving the blockage of a blood vessel caused by a clot or other foreign material, impacting blood flow.
Cauda Equina: Refers to the nerve fibers at the lower end of the spinal cord, resembling a horse's tail, essential for lower body function.
Glial Cells: Supportive cells in the nervous system that play key roles in maintaining homeostasis, forming myelin, and providing support and protection for neurons.

Brain Structure and Function

Thalamus: Functions as a central relay station in the brain, processing and distributing sensory and motor signals to the cerebral cortex.
Synapse: The small gap between nerve cells where neurotransmitter exchange occurs, vital for nerve impulse transmission.
Plexus: Networks formed by interlacing blood vessels or nerve fibers, crucial for efficient signal transmission and blood flow regulation.

Neurotransmission and Neurophysiology

Acetylcholine: A neurotransmitter that plays a significant role in muscle activation and parasympathetic nervous system functions.
Neurasthenia: A condition characterized by persistent weakness and fatigue, often related to nerve issues.
Dysphasia: A language disorder that results in difficulty with speech, affecting communication abilities.

Pain and Motor Functions

Analgesia: A state of insensitivity to pain, often achieved medically to help manage discomfort.
Hemiplegia: A condition involving partial paralysis affecting either the right or left side of the body, impacting movement and sensation.
Radiculitis: Inflammation occurring in the roots of spinal nerves, typically causes pain and neurological symptoms.

Nerve Disorders

Neuropathy: A broad term for nerve disease that can lead to weakness, numbness, and pain, typically in the hands and feet.
Vagotomy: A surgical procedure involving the incision of the vagus nerve, impacting digestive functions.
Ataxia: A neurological sign consisting of lack of voluntary coordination, often affecting gait and balance.
Dysesthesia: A distressing condition characterized by abnormal sensations, including pain, often linked to nerve dysfunction.
Glioma: A type of tumor arising from immature brain cells, classified based on the type of glial cell involved.

Diagnostic Tools

Electroencephalogram (EEG): A diagnostic test that measures electrical activity in the brain, utilized to identify various neurological conditions.
