CNS
This term describes the quality of one side of the brain being associated with the sensory and motor functions of the opposite side of the body
What is contralateral?
This type of sensory receptor senses pain; its Latin prefix is derived from the work nocere, meaning "to injure"
What is a nociceptor ?
This division of the ANS arises from the cranial nerves and sacral spinal cord
What is the parasympathetic NS?
This lobe of the cerebrum is involved in general sensory input and balance
What is the parietal lobe?
This type of brain fiber connects different areas of the same hemisphere
What are association fibers?
Damage to this area of the brain causes non-fluent aphasia; word choice is appropriate, but word formation is highly effortful
What is Broca's area?
This type of simple receptor triggers the muscle stretch reflex; they will cause contraction in a muscle that is stretching too forcefully
What are muscle spindles?
The effector of this division of the nervous system are the skeletal muscles
What is the somatic NS?
Damage to this area of the brain can cause fluent aphasia; words are effortless, but meaning is impaired
What is Wernicke's area?
This division of the ANS arises from the thoracic region of the spine, which allows for rapid signaling to the visceral organs
What is the SNS?
This term refers to an area of the brain that interprets and understands sensory input; damage to the visual type of this area may cause prosopagnosia, or face blindness
What is an association center?
Stimulation of nociceptors will trigger the release of these two substances, which are related to the sensation of pain
What are glutamate and substance P?
This area of the brain regulates the balance between the PNS and SNS
What is the hypothalamus?
You may have increased levels of this brain wave when the only part of the exam you feel confident on is your name
What are theta waves?
This population generally has a higher pain tolerance, as their brain has dramatically restructured itself to perceive pain differently
What are mothers?
Aphasia of this motor language area preserves understanding, but makes speech broken and non-fluent
What is Broca's area?
This cranial nerve has the most cutaneous sensory distribution of any cranial nerve; it is involved with the muscles of mastication, and is often numbed with Novocain at the dentist
What is the trigeminal nerve (cranial nerve V)?
This type of acetylcholine receptor can be either stimulatory or inhibitory; it is named for the first isolated parasympathomimetic substance, which was derived from a mushroom
What is a muscarinic receptor?
This area of the cerebral cortex learns, memorizes, plans, and coordinates motor skills
What is the premotor cortex?
The layman's term for this nerve is a misnomer, as it is not a bone and it's not funny when you're the one to hit it
What is the ulnar nerve?
This horn, root, and ganglion of the spinal cord are associated with sensory afferent signals; this word may also remind you of the characteristic fin of a dolphin or shark
What is dorsal?
These interlacing spinal nerve networks are found in the cervical, brachial, lumbar, and sacral regions, lateral to the spinal column
What are plexuses?
This gland is only innervated by the SNS; it secretes epinephrine and norepinephrine into the blood
What is the adrenal medulla?
This most inferior aspect of the brain stem is associated with several essential life functions, including heart rate, respiratory rate, and vomiting
What is the medulla oblongata?
This nerve of the cervical plexus innervates the diaphragm; it can cause the feeling of "having the wind knocked out" of you, and spinal injury at this level can cause respiratory arrest
What is the phrenic nerve?
