enteric nervous system

which neurotransmitter is associated with cholinergic receptors

acetylcholine

which adrenergic exhibits primary inhibitory effects

B2 receptors

T/F

The parasympathetic division of ANS functions to maintain homeostasis during exercise or fight or flight

F

Division primary concerned with conserving energy and replenishing nutrients

parasympathetic

The motor division of the autonomic nervous system has _______ neurons in each pathway

two

the somatic sensory portion includes

detection of vision, hearing, smell, and taste

the somatic motor portion involves initiation and transmission of nerve signals from

CNS to control skeletal muscle

somatic nervous system effectors are

skeletal muscle fibers

Sensory input of Somatic NS

special senses, skin, proprioceptors

Autonomic NS sensory output

visceral sense

Somatic Nervous System Effectors

skeletal muscle fibers

Autonomic Nervous System Effectors

Cardiac muscle cells, smooth muscles cells, glands

CNS region of control Somatic Nervous System

cerebrum, thalamus, cerebellum, brainstem, spinal cord

CNS region of control Autonomic Nervous System

hypothalamus, brainstem, spinal cord, cerebrum, thalamus, limbic system

Number of Neurons in pathways of SNS

one neuron from CNS, somatic neuron axon extends from CNS to effector

Number of Neurons in pathways of ANS

two neurons from CNS, pre-ganglionic axon projects to ganglionic neuron, ganglionic neuron has post-ganglionic axon projects to effector

SNS axon properties

myelinated, thicker in diameter, fast nerve signal propagation

ANS axon properties

pre-ganglionic are myelinated/ smaller in diameter

post-ganglionic are un-myelinated/smaller in diameter

slow nerve signal propagation

SNS neurotransmitter release

Acetylcholine (ACh)

ANS neurotransmitter release

pre-ganglionic axon release ACh

post-ganglionic axons release ACh or norepinephrine

response of effector SNS

excitation only

response of effector ANS

excitation or inhibition
