Week 3-Chapter 10 Flashcards
Analgesics
Drugs that reduce pain
Biofeedback
A measurement of physiological responses that yields information about the relationship between the mind and the body and helps people manipulate those responses through mental activity
Bell’s palsy
Disorder that affects the facial nerve
Carpal tunnel syndrome
A condition that affects the median nerve and the flexor tendons that attach to the bones of the wrist
Cranial nerves
12 nerves originating from the brain stem that each have a specific function
Congenital insensitivity to pain
A birth defect in which there is insensitivity to pain. Anhidrosis, or the inability to sweat, and intellectual disability
Charcot Marie tooth disease
The most common inherited neurological condition, which is caused by a gene defect, symptoms include hammer toes, high foot arch, and foot drop. Also called hereditary motor and sensory neuropathy
Effectors
The responding organs to a stimulus, which may be in the form of movement
Ganglia
A mass of nerve cell bodies outside the central nervous system
Femoral nerve
Found in the lumbar plexus, it stimulates the hip and leg
Mixed nerve
Nerve composed of both afferent (sensory) fibers and efferent (motor) fibers
Motor nerve (efferent nerve)
Nerve fiber that carries impulses from the brain or spinal cord to muscles, organs, or glands
Electromyography (EMG)
Device used to measure electrical muscle activity
Neuralgia
Severe, stabbing pain along the pathway of a nerve
Neuritis
Inflammation of a nerve
Parasympathetic system
Division of the autonomic nervous system that inhibits or opposes the effects of the sympathetic nervous system
Phrenic nerve
Nerve that controls the diaphragm and intercostal muscles
Paresthesia
Sensation of tingling, crawling, or burning of the skin
Peripheral neuropathy
Term used to describe damage to the peripheral nerves
Plexus
A network of spinal nerves
Receptors
Sensory nerves that receive a stimulus and transmit it to the central nervous system
Sciatica
Neuritis of the sciatic nerve
Reflex
Involuntary action, automatic response
Radial nerve
Nerve found in the brachial plexus that stimulates the wrist and hand
Sciatic nerve
Largest nerve in the body, originates in the sacral plexus and runs through the pelvis and down the leg
Sensory nerve (afferent nerve)
Nerve fibers that carry messages from the sense organs to the brain and spinal cord
Trigeminal neuralgia
Painful condition affecting the fifth cranial nerve, also known as tic douloureux
Sympathetic system
Division of autonomic nervous system
Stimulus
Any change in the environment
Spinal nerves
31 pairs, they originate in the spinal cord
Somatic nervous system
A division of the peripheral nervous system, it conducts impulses from the brain and spinal cord to the skeletal muscles, thereby causing responses to changes in our external environment
