Chapter 8: Central Nervous System Flashcards
The limbic system encircles the top of the
Brainstem
The limbic system influences ______
Unconscious and instinctive behaviors
This behavior is modified by the
Cerebral Cortex
A part of the limbic system is the
Olfactory Bulb
Carries impulses from the sensory neurons to the motor neurons
Associative Neurons
The extension of the neuron that carries the messages away from the nerve cell body
Axon
The type of nervous tissue that insulates and supports the nerve
Neuroglia (“nerve glue”)
The ability of a neuron to react to stimuli
Irritability
Neurons that carry messages to the brain and spinal cord
Afferent Neurons
The extensions of the neuron that take messages to the cell body
Dendrites
The two main communication systems of the body are the nervous system and the
Endocrine System
Neurons that carry messages from the brain and spinal cord
Efferent Neurons
The area where messages go from the axon of one cell to the dendrite of another
Synapse Cleft
The neurotransmitter between muscle cells and nerve cells
Acetylcholine
The inflammation of the linings of the brain and spinal cord
Meningitis
An inflammation of the brain
Encephalitis
A seizure disorder of the brain, characterized by a recurring and excessive discharge from neurons
Epilepsy
A disturbance in voluntary muscular action due to brain damage
Cerebral Palsy (CP)
A contagious viral disease of the nerve pathways of the spinal cord that causes paralysis
Poliomyelitis
A condition that involves an increased volume of cerebrospinal fluid within the ventricles of the brain due to a blockage
Hydrocephalus
A disorder that causes rhythmic shaking (is progressive, often inherited disorder that occurs in later adulthood)
Essential Tremor
An autoimmune, chronic inflammatory disease of the central nervous system in which the immune cells attack the myelin sheath of nerve cell axons
Multiple Sclerosis (MS)
A mosquito-borne virus
West Nile Virus (WNV)
Is defined as a loss in at least two areas of complex behavior, such as language, memory, visual and spatial abilities, or judgement that significantly interferes with a person’s daily life
Dementia
