Nervous System 3 Flashcards
Involuntary autonomic nerves that regulate normal body functions such as heart rate, breathing and digestion
Parasympathetic nerves
Autonomic nerves that influence bodily functions involuntarily in terms of stress
Sympathetic nerves
Carries messages to the brain and spinal cord from receptor; afferent nerve
Sensory nerve
Carrie‘s messages from brain and spinal cord to muscles and organs; efferent nerve
Motor nerve
Posterior portion of the brain that connects the cerebrum with the spinal cord: includes the mid brain, pons and medulla oblongata
Brainstem
Excessive sensitivity to pain
Algesia
Absence of sensitivity to pain
Analgesia
Pain
Algia
Feeling, nervous sensation
Esthesia
Movement
Kinesia
Seizure
Lepsy
Sight paralysis
Paresis
Speech
Phasia
Paralysis
Plegia
Action
Praxia
Strength
Sthenia
Brain disorder with progressive deterioration of mental capacity; personality changes and impairment of daily functioning
Alzheimer disease
Degenerative disorder of motor neurons and spinal cord and brain stem leading to progressive muscular paralysis; Lou Gehrig’S disease
Amyotrophic lateral sclerosis
Covering of white fatty tissue that surrounds and insulate the axon of a nerve cell; speeds impulse conduction
Myelin sheath
Microscopic cord-like collection of fibres (axons and dendrites) they carry electrical impulses
Nerve
An organ that receives a nervous stimulus and passes it onto afferent nerve, example the skin, ears, eyes and taste buds
Preceptor
Nerve root
Radicul/o
Imaging technique that uses magnetic waves and radio frequency waves to create images of the brain and spinal cord
Magnetic resonance imaging
Recording of the electrical activity within the brain
Electroencephalography
Cross-sectional x-ray images of the brain and spinal cord (with and without contrast)
Computed tomography scan
Condition of decreased coordination caused by cerebellum disorder
Ataxia
Slowness of movement
Bradykinesia
Abnormal nervous sensation without appearance, cause example, tingling, numbness, prickly
Paresthesia
Inflammation of many nerves
Polyneuritis
Three protective membranes that surround the brain is spinal cord
Meninges
Skull
Crani/o
Head
Cephal/o
