nervous system

Stack #100453

site of origin for autonomic nervous system brain or lateral horn of spinal cord
number of neurons from origin in CNS to effector organ two-neuron chain preganglionic and postganglionic
organs innervated in the autonomic nervouos system cardiac muscle, smooth muscle, exocrine and some endocrine glands
type of innervation of ANS most effector organs dually innervated by the two antagonistic branches of this system (sympathetic and parasympathetic)
neurotransmitter at effector organs for the ANS may be acetylocholine (parasym) or NE at the sym terminals
effects on Effector organs in the autonomic nervous system either stimulation or inhibition (antagonistic actions of two branches)
what type of control does the ANS have under involuntary coontrol; may be voluntarily controlled with biofeedback techniques adn training
what are the highere centers involved in control in the ANS spinal cord, medulla, hypothalamus, prefrontal association cortex
what is the Site of origin for the somatic nervous system ventral horn of spinal cord for most; those supplying muscles in head orginate in brain
number of neurons from origin in CNS to effector organ in the somatic nervous system single neuron (motor neuron)
organs the somatic nervous system innervates skeletal muscle
type of innervation in the somatic nervous system effector organs innervated only by motor neurons
neurotransmitter at effector organs in the somatic nervous system only acetylcholine
effects on effector organs in the somatic nervous system stimlation only (inhibition possibly only centrally through IPSP on cell body of motor neuron
types of control in the somatic nervous system subject to voluntary control; much activity subconsciously coordinated
higher centers involved in control in the somatic nervous system spinal cord, motor cortex, basal nuclei, cerebellum, brain stem
