Week 7 Neurological & Endocrine Disorders Flashcards
____ carry impulses to the spinal cord and brain from all parts of the body
sensory (afferent) neurons
____ carry impulses from the brain and spinal cord to glandular and epithelial tissue
motor (efferent) neurons
____ conduct impulses from sensory neurons to motor neurons
interneurons
____ support neurons
glia
parts of the brainstem (3)
medulla oblongata
pons
midbrain
parts of the diencephalon (3)
hypothalamus
thalamus
pineal gland
tough, fluid-cushioned set of membranes that safeguard nervous system organs
meninges
tough outer layer that lines the cranium and vertebral column
dura mater
innermost membrane covering the brain and spinal cord
pia mater
membrane between the dura mater and the pia mater that resembles a cobweb
arachnoid mater
an infection of the cerebrospinal fluid, usually caused by a virus or a bacterium
meningitis
excessive accumulation of cerebrospinal fluid in the ventricles of the brain caused by a lack of drainage or absorption
hydrocephalus
inflammation of the brain; technically refers to an infection of the brain caused by a virus
encephalitis
type of encephalitis where a virus invades the brain directly
primary encephalitis
type of encephalitis where a virus infects another part of the body first
secondary encephalitis
meningitis can be contagious (T/F)
true
inflammation of the spinal cord; result of infection, necrosis, or demyelination of the spinal cord
myelitis
demyelination of the spinal cord
transverse myelitis
inflammation of a nerve or nerves; may be caused by trauma, infection, or poisoning
neuritis
recurrent degenerative disorder of the nervous system resulting in seizures
epilepsy
repetitive electrical discharges within the brain
seizure
type of seizure characterized by incontinence, uncontrolled contraction of muscles, loss of consciousness
grand mal
type of seizure where an individual ceases activity for a few seconds
petite mal
infection of the nervous system caused by the rabies virus
rabies (hydrophobia)
rabies can cause paralysis and can be fatal (T/F)
true
autoimmune inflammatory disease of the central nervous system; lymphocytes degrade the myelin sheath of the nerves
multiple sclerosis
the average lifespan with multiple sclerosis is approximately 10 years (T/F)
false (average lifespan is 30+ years)
chronic nervous disease characterized by a slowly spreading tremor, muscular weakness and rigidity, and a peculiar gait
Parkinson’s disease
Parkinson’s disease results in diminished levels of ____ which causes a tremor
dopamine
an expressionless face, speech issues, a bowed head, forward bend to the body, and thumbs turned inward are indications of ____
Parkinson’s disease
common form of dementia that involves the parts of the brain that control thought, memory, and language
