Autonomic Nervous System Flashcards
Nervous system (2)
somatic and autonomic
somatic nervous system is (3)
sensory to skin body walls limbs, motor to skeletal muscle, conscious/voluntary
autonomic nervous system is (3)
viscera blood vessels glands smooth muscle innervation, subconscious/involuntary, 2 neurons from spinal cord to target
somatic nervous system made of (2)
sensory and motor
autonomic nervous system made of (2)
sympathetic and parasympathetic
sensory innervation (4)
pain, pressure, stimuli, touch
motor innervation (2)
skeletal muscle and movement
sympathetic innervation (9)
thoraco lumbar, energy mobilisation, fight/flight, bronchodilation, vasoconstriction, increased HR, decrease glandular secretion, increase sweat, decrease GI motility
parasympathetic innervation (6)
cranio-sacral, conserve energy, bronchoconstriction, decrease HR, increase glandular secretions, decrease sweating, increase GI motility
What do somatic sensory neurons do
touch, pain, pressure information from periphery to CNS
What do somatic motor neurons do
movement information from CNS to skeletal muscle
Somatic nervous system elements (10)
dorsal horn, ventral horn, ventral root, dorsal root, dorsal root ganglion, spinal nerve, sympathetic ganglion, sympathetic trunk, dorsal ramus, ventral ramus
somatic sensor elements (3)
from skin, dorsal over middle back/venterolateral body and limbs
somatic motor elements (3)
To muscles, dorsal adjacent to vertebra/venterolateral body and limbs
ANS elements (4)
cervical ganglia, sympathetic trunk, spinal cord, brainstem
sympathetic nerve features (2)
short preganglionic, synapse with postganglionic in sympathetic trunk/prevertebral/visceral ganglia
sympathetic supply with postaganglionic neurons in the sympathetic trunk (2)
head and thorax
postganglionic neurons in the visceral ganglia
abdomen
sympathetic neurons to the head run through
cervical ganglia
sympathetic neurons through which nerve to abdomen and pelvic viscera
splanchnic
sympathetic prganglionic body location (3)
intermediolateral nucleus, lateral horn, T1-L2/3
sympathetic pre and post ganglionic synapses
sympathetic ganglion, cevical sympathetic ganglia x2, visceral ganglion
