Peristalsis
A response of the parasympathetic division, this is involuntary smooth muscle contraction in the walls of the intestines, which propels food bolus onward.
Preganaglionic
Both the sympathetic and parasympathetic division of the ANS have _____________ neurons that release ACh and bind to nicotinic receptors.
Adrenal Gland
Gland that sits on top of the kidney and secretes hormones.
Sympathetic Parasympathetic
Name the two divisions of the Autonomic Nervous System.
Somatic
The ___________ nervous system innervates skeletal muscle.
Efferent
The ___________ pathways of the ANS contain autonomic ganglia.
Somatic Nervous System
The division of the peripheral nervous system that controls the body's skeletal muscles.
Autonomic Nervous System (ANS)
The division of the peripheral nervous system that innervates glands, smooth muscle, and cardiac muscle.
Postganglionic
The effectors of the ANS are innervated by the _____________ Neuron.
Postganglionic
The efferent neuron of the ANS that comes after the autonomic ganglion is called the ____________ Neuron.
Preganglionic
The efferent neuron of the ANS that comes before the autonomic ganglion is called the ____________ Neuron.
Short
The parasympathetic division has a __________ postganglionic neuron.
Long
The parasympathetic division has a __________ preganglionic neuron. (referring to length)
Craniosacral
The parasympathetic division has a _______________ origin.
Ganglia
The somatic nervous system does not contain __________ in the motor (efferent) pathway.
Voluntary
The somatic nervous system is _____________. (Choose one: voluntary or involuntary)
ACh (Acetylcholine)
The somatic nervous system releases this neurotransmitter.
short
The sympathetic division has a _______ preganglionic neuron. (referring to length)
Long
The sympathetic division has a ________ postganglionic neuron. (referring to length)
Thoracolumbar
The sympathetic division originates from the _______________ region of the spinal cord.
Parasympathetic
This division of the ANS causes decreased heart rate.
Sympathetic
This division of the ANS has a *long* postganglionic neuron.
Parasympathetic
This division of the ANS has a *long* preganglionic neuron.
Parasympathetic
This division of the ANS has a *short* postganglionic neuron.
Sympathetic
This division of the ANS has a *short* preganglionic neuron.
Parasympathetic
This division of the ANS has a craniosacral origin.
Sympathetic
This division of the ANS has a neurotransmitter that binds to adrenergic receptors on the effectors.
Parasympathetic
This division of the ANS has a postganglionic neuron that releases ACh.
Sympathetic
This division of the ANS has a postganglionic neuron that releases Norepinepherine.
Sympathetic
This division of the ANS increases heart rate.
Parasympathetic
This division of the ANS is involved with defication. (relaxing of the sphincter)
Parasympathetic
This division of the ANS is involved with digestive salivation.
Parasympathetic
This division of the ANS is involved with gastric secretion and contractions.
Parasympathetic
This division of the ANS is involved with lethargy.
Sympathetic
This division of the ANS is involved with the Fight, Flight, and Fright response.
Parasympathetic
This division of the ANS is involved with the rest, digest, and "restroom" response.
Parasympathetic
This division of the ANS is involved with urination. (contracting of the bladder)
Parasympathetic
This division of the ANS will cause decreased breathing.
Sympathetic
This division of the ANS will cause pupil dilation.
Sympathetic
This division of the ANS will cause vasoconstriction in skin.
Parasympathetic
This division of the ANS will cause vasodilation in abdominal viscera.
Sympathetic
This division of the ANS will cause vasodilation in cardiac and skeletal muscle.
Sympathetic
This division of the ANS will demonstrate lypolysis.
Sympathetic
This division of the ANS will increase respiration.
Sympathetic
This division of the ANS will stimulate platelets which keeps them alert and prepared for damage.
Parasympathetic
This division of the ANS, has a neurotransmitter that binds to muscarinic receptors on the effectors.
Autonomic Nervous System
This division of the peripheral nervous system uses both ACh and Norepinepherine as its neurotransmitter.
Parasympathetic
This divison of the ANS is involved with peristalsis.
Parasympathetic
This divison of the ANS is will cause pupil constriction.
Sympathetic
This divison of the ANS orginates from the thoracolumbar region of the spinal cord.
Adrenergic
When epinepherine is released by the adrenal gland into the blood stream, it binds to ___________ receptors on the effector.
Sympathetic
When epinepherine is released by the adrenal gland, it acts as a hormone wth a __________ effect. (prolonged and slower effect)
sensory afferent
input
motor efferent
output
