The ANS includes what divisions?

Enteric

Sympathetic

Parasympathetic

All of the above

The ANS is controlled by cells in the periventricular zone of the thalamus

True

False

Actions of the ANS are typically multiple, diverse, and faster acting than that of the SMS

True

False

The hypothalamus serves to integrate somatic as well as autonomic functions.

True

False

Neurosecretory neurons......

Influence the posterior pituitary directly

Influence the posterior pituitary indirectly

Influence the anterior pituitary directly

None of the above

The Suprachiasmatic nucleus (SCN) Lies just above the optic chiasm; receives input from the retina and serves to synchronize circadian rhythms with light-dark cycles

True

False

The hypothalamus is found below and posterior to the thalamus

True

False

Axons of Magnocellular neurosecretory cells extend to the posterior lobe

True

False

Oxytocin does all of the following except...

Causes the uterus to contract

Facilitates delivery

Acts on kidneys

Stimulates milk let down

Vasopressin acts on the kidneys to excrete water and increase urine output

Vasopressin is a hormone associated with the anterior pituitary.

True

False

The brain and kidneys communicate with each other, especially when blood volume and blood pressure spike.

True

False

The anterior lobe of the pituitary is an actual gland (in contrast to the posterior lobe which is part of the brain)

True

False

The Anterior Pituitary is under control of what type of cell?

Magnocellular

Parvocellular

Axons extend to the anterior pituitary.

True

False

The Anterior Pituitary communicates indirectly via the...

Bloodstream

Portal circulation system

All of the above

The Anterior pituitary is a true gland, while the posterior pituitary isn't

True

False

The Follicle-stimulating hormone's action is to

Stimulate protein synthesis

Ovulation, spermatogenesis

Inhibit immune system

Growth and milk secretion

The Growth hormone targets all cells, and stimulates protein synthesis.

True

False

Cortisol inhibits the immune system and mobilizes energy reserves.

True

False

The ANS' functions are much more complex than those of the SMS

True

False

The ANS innervates all of these types of tissues except..

Glands

Smooth muscle

Cardiac muscle

Skeletal muscle

The cell bodies of lower motor neurons in the ANS lie within the PNS

True

False

Preganglionic fibers in the ANS lie within the CNS

True

False

The SMS uses what kind of pathway?

Disynaptic

Monosynaptic

Where do preganglionic axons of the sympathetic division emerge from?

Brain stem

Sacral segments of spinal cord

Middle third of spinal cord

The physiological actions of the sympathetic and parasympathetic divisions are usually opposed each other (for example, if the sympathetic division speeds up the heart rate, the parasympathetic division slows it down)

True

False

The sympathetic division is associated with stress or crisis type behaviors such as fight, flight, fright, or sex

True

False

The parasympathetic division facilitates several non-crisis processes such as digestion, growth, energy storage, and immune responses

True

False

All tissues receive both sympathetic and parasympathetic innervation.

True

False

Postganglionic neurons of both sympathetic and parasympathetic divisions use acetylcholine (ACh) as a neurotransmitter

True

False

Postganglionic parasympathetic neurons release ACh, and the effects are widespread, acting entirely through mAChRs

True

False

Postganglionic sympathetic neurons release norepinephrine (NE)

True

False

Drugs that are sympathomimetic......

Promote the muscarinic actions of ACh

Inhibit the actions of NE

Promote the actions of NE

Mimick activation of the parasympathetic division of the ANS

Propranolol is a Parasympathomimetic drug

Truen

False

Atropine is a Parasympathomimetic drug

True

False

The ANS receives input from the nucleus of the solitary tract located in the cortex.

True

False

The Enteric division is made up of three networks, or plexuses

True

Falsw

The Locus Coeruleus deals with which neurotransmitter?

Dopamine

ACh

Serotonin

The Raphe Nuclei is in the midbrain

True

False

The Substantia Nigra and Ventral Tegmental Area deal with the neurotransmitter Dopamine

True

False

The noradrenergic Locus Coeruleus is located in the....

Hypthalamus

Pons

Midbrain

Medulla & pons

The Locus Coeruleus Involved in regulation of attention, arousal, sleep-wake cycles, learning and memory, anxiety, pain, mood, and brain metabolism

True

False

NE can make cerebral cortex neurons more responsive to sensory stimuli, make them hyperpolarize easier

True

False

The Raphe Nuclei, along with the locus coeruleus make up the ascending reticular activating system

True

False

All of the following are true of The Raphe Nuclei except

Involved in the control of sleep-wake cycles, as well as the different stages of sleep

These neurons appear to be involved with mood and emotional behavior

These neurons are the most quite during sleep

Involved with regulation of pain

Neurons of the SN innervate regions of the cerebrum that includes the frontal cortex and parts of the limbic system (fear, emotion)(higher thinking)

True

False

Another name for the Globus Pallidus is the striatum

True

False
