Flashcards in Neurophys Physiology Deck (28):
Name of nerve ending found in deep subcutaneous tissue and detects joint position sense
Ruffini endings which are Group 1 nerve endings
Name the nerve ending that is found in muscle and detect changes in the length of the muscle.
Muscle spindle with is goup Ia nerve ending
Name the nerve ending that is found in tendons and joints to detect load or tension.
Golgi tendon organs and is group Ib nerve endings
Name the nerve ending that are found deep subcutaneous tissue and joints and detects vibrations
Pacinian corpuscles which are group II nerve endings
Name the nerve endings that are found in the epidermis and detect crude touch and pressure.
Merkel cells which are group III nerve endings
Name the nerve endings that are found in the epidermis, dermis, joints and detect pain and temperature.
Naked nerve endings and are group IV
Name the nerve that is in the dermal papillae and detect two-point discrimination(fine touch).
Name the nerve endings that are in the dermis and the cornea and detect light touch.
Which neurotransmitters are inhibitory within the CNS?
Glycine (spinal cord) and GABA (brain)
Which type of cholinergic receptors are found at the neuromuscular junction and most of all cholinergic receptors?
Which type of cholinergic receptors are found at the parasympathetic postganglionic endings?
Which type of receptor is found in smooth muscle in blood vessels, gut, sphincter and skin. It constricts.
alpha-1 adrenergic receptor
What type of receptor is found in the islets of Langerhan's and decreases insulin secretion?
alpha-2 adrenergic receptors
Which type of receptor is found in the cardiac muscle and increases rate and force and in the kidney?
beta-1 adrenergic receptor
Which type of receptor is found in the smooth muscle in bronchi, coronary vessels and skeletal muscle and dilates them?
beta-2 adrenergic receptor
Which receptor is found in brown fat and increases lipolysis?
beta-3 adrenergic receptors
Which type of nociceptor is fast conducting, mostly A fibers, produce well localized, sharp, pricking pain?
Specific: Mechanical, cold thermal, heat thermal
Which nociceptor is present in healthy tissue and is not activated by noxious stimuli? It will only begin firing when tissue becomes increasingly inflamed.
Which nociceptor is mostly group IV and C type fibers, found in somatic and visceral tissue, may be activated by chemical, thermal or mechanical stimuli?
Which nociceptor have receptors for bradykinin, prostaglandin E2, serotonin, histamine, interleukin and TNF?
Which nociceptor is slow conducting and causes poorly localized burning and dull aching pain?
Which function do A-alpha type nerve fibers do?
Motor to skeletal muscle
What function do A-beta type nerve fibers do?
Fine touch, vibration, proprioception
What function do A-gamma type nerve fibers have?
What function do A-delta type nerve fibers have?
Fast pain, temperature and touch
What function do B type nerve fibers have?
Preganglionic autonomic fibers
What function do C type nerve fibers have?
Postganglionic fibers; slow pain
