conducts electrical currents toward the cell body


releases neurotransmitters

myelin sheaths

location of the nucleus

slight and transient brain injury


traumatic injury that destroys brain tissue


total nonresponsivness to stimulation

intracranial hemorrhage

may cause medulla oblogata to be wedge into foramen magnum by pressure of blood

cerebral edema

after head injury, retention of water by brain

cerebrovascular accident

results when a brain region is deprived of blood or exposed to prolonged ischemia

alzheimers disease

progressive degeneration of the brain with abnormal protein deposits

multiple sclerosis

autoimmune disorder with extensive demyelination

transient ischemic attack

a mini-stroke, fleeting symptoms of a CVA

cutaneous sense organs

sensory receptors found in the skin, which are specialized to detect temperature, pressure changes, and pain

schwann cells

specialized cells that myelinate the fibers of neurons found in the PNS


junction or point of close contact between neurons


bundle of nerve processes inside the cns

association neuron

neuron, serving as part of the conduction pathway between sensory and motor neurons

nodes of ranvier

gaps in a myelin sheath


collection of nerve cell bodies found outside the cns

efferent neuron

neuron that conducts impulses away from the cns to muscles and glands


sensory receptors found in muscle and tendons that detect their degree of stretch


changes, occurring within or outside the body, that affect nervous system functioning

afferent neuron

neuron that conducts impulses toward the CNS from the body periphery


chemicals released by neurons that stimulate other neurons, muscles, or glands


support, insulate, and protect cells

demonstrate irritability and conductivity



release neurotransmitters


are amitotic


able to divide; therefore are responsible for most brain neoplasms
