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

sensory afferent

input

motor efferent
