the study of behavior and the function and processes of the mind

means pertaining to the mind

the study of the processes and function of the body

sensory receptors that detect changes that occur inside and outside the body; some receptors monitor changes such as changes in room temp, and other receptors monitor changes within the body such as body temperature

signals to muscles and glands to cause an effect

the part of the nervous system under conscious or voluntary control

the part of the nervous system that relates to involuntary or autonomic body functions

the control center, includes the brain and spinal cord

consists of the various nerve processes that connect the brain and spinal cord with receptors, muscles and glands

connects the cerebrum with the spinal cord

what are the 3 parts of the brain stem?

what are the major structures of the brain?

nerve endings that detect chemicals

located immediately under the skin, detects changes in temperature

responsible for vision

the tough white membrane covering much of the eyeball

means pertaining to tears

refers to the production and discharge of tears

this duct carries tears to the nasal cavity and explains why a runny nose often accompanies crying

the convex, transparent structure at the front of the eyeball

located on the posterior part of the eye, contains photoreceptors (rods and cones)... it's continuous with the optic nerve, which carries the impulse to the cerebrum and enables vision

in the inner ear, contains receptors that enable us to hear

enables us to maintain a sense of balance

a nerve cell that has dendrites and an axon

the fluid that surrounds the brain and the spinal cord

the recording and analysis of electrical activity of the brain

record obtained from an electroencehaphography

blood accumulates in the epidural space, the space outside the dura mater

accumulation of blood beneath the dura mater

bleeding occurs within the brain

stroke or stroke syndrome; normal blood supply to the brain has been disrupted; results in insufficient oxygen to brain tissue and is caused by hemorrhage, occlusion (closing), or constriction of the blood vessels that supply normally supply oxygen to the brain

warning signs preceding strokes; caused by a brief interruption in cerebral blood flow; symptoms include disturbance of normal vision, dizziness, weakness and numbness

fluid accumulation in the skull, caused by disorders such as brain tumors that interfere with the flow of CSF

complete or partial loss of muscle movement

partial or complete loss of sensation with or without loss of consciousness; results from disease, injury, or administration of an anesthetic

inability or refusal to swallow; characterized by abstention from eating because swallowing is painful

headache

loss of consciousness, either temporary or prolonged, as a result of a blow to the head

bruising of brain tissue as a result of head injury

the result of the rupture of a sclerosed or diseased blood vessel in the brain

a brain disorder characterized by paralysis and lack of muscle coordination; it results from developmental defects in the brain or trauma at birth

a state of unconsciousness from which the patient cannot be aroused, even by powerful stimulation

protrusion of the brain through a defect in the skull

paralysis affecting like parts on both sides of the body
