subdural hematoma

collection of blood in the space below the dura mater surrounding the brain

Epidural Hematoma

Collection of blood located above the dura mater

Myoneural

Pertaining to muscle and nerve

analgesia

Absence of sensitivity to pain

Cephalgia

Head pain; Headache

causalgia

Intense burning pain

anesthesia

Absence of nervous feeling or sensation

hyperesthesia

excessive sensitivity or feeling

Spelling of EXCESSIVE MOVEMENT

H Y P E R K I N E S I S

hyperkinesis

excessive movement

paresthesia

Abnormal nervous sensation occurring w/o apparent cause (pins and needles)

narcolepsy

sudden seizures of sleep

dyslexia

Difficulty in reading, writing, and learning

hemiparesis

slight paralysis in left or right of the body

aphasia

Inability to speak; damage to cerebral cortex

paraplegia

paralysis of the lower part of the body (both legs)

quadriplegia

paralysis of all four limbs (arms and legs)

syncopal

pertaining to fainting

ataxia

without coordination

hydrocephalus

abnormal accumulation of cerebrospinal fluid in the ventricles (canals) of the brain

multiple sclerosis

chronic neurologic disorder marked by destruction of the myelin Seath on axons in the CNS

dementia

mental decline or deterioration

spina bifida

Congenital defects in the lumbar spinal column caused BY IMPERFECT UNION of vertebral parts (neural defect)

epilepsy

chronic brain disorder characterized by recurrent seizure activity

Parkinsons disease

degeneration of neurons in the basal ganglia, occurring in later life and leading to tremors, weakness of muscles and slowness of movement

meningitis

Inflammation of the meninges

cerebral concussion

type of traumatic brain injury caused by a blow to the head

cerebral contusion

bruising of brain tissue resulting from direct trauma to the head

CVA

cerebrovascular accident (stroke) aka, cerebral infarction

lumbar puncture

AKA spinal tap - process of obtaining a sample of cerebrospinal fluid by inserting a needle into the subarachnoid space of the lumbar region to withdraw fluid

Central nervous system (CNS)

brain and spinal cord

peripheral nervous system (PNS)

the sensory and motor neurons that connect the central nervous system to the rest of the body

Two parts of the PNS

somatic and autonomic

somatic

the division of the peripheral nervous system that controls the body's skeletal muscles

autonomic

A subdivision of the peripheral nervous system. Controls involuntary activity of visceral muscles and internal organs and glands. consists of parasympathetic and sympathetic

parasympathetic

Part of the autonomic (involuntary) nervous system which produces effects such as decreased blood pressure and heart rate (rest and digest)

sympathetic

the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations (fight or flight)

cerebellum

muscle coordination

cerebrum

largest part of the brain, intellect language and vision; nerve cells called cerebral cortex

Thalamus

RELAY CENTER; Integrates and monitors impulses from skin (pain

Hypothalamus

Emotion, sleep, appetite; endocrine system (pituitary gland) tic ne

Pons

Bridges the cerebrum and cerebellum with the rest of
the brain

Midbrain

upper part brainstem; Contains pathways connecting the cerebrum with lower portions of brain

Medulla Oblongata

heartbeat, respiration, blood pressure; Connects the spinal cord to the brain, Nerve tracts from side to side

dura mater

Outer most layer of meninges; protects spinal cord and brain;

occipital lobe

vision

thrombosis

formation of a blood clot (thrombus) inside one of your blood vessels or a chamber of your heart
