Chapters 14, 15, 16

The medulla oblongata

The respiratory rhythm center is located in the:

Red Nuclei

The regions of the mesencephalon that issue subconscious motor commands that affect upper limb position and background muscle tone are the:

E) All of these

Which of the following is a function of the hypothalamus?
A) Regulates body Temp
B) Secretes oxytocin
C) Produces ADH
D)Controls autonomic centers
E) All of these

Cerebellum

Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the:

12

There are ( ) pairs of cranial nerves

Falx Cerebri

The dural fold that projects into the longitudinal fissure between cerebral hemispheres is called the:

No

Could someone who had their corpus callosum cut be able to identify something placed in their left hand?

General interpretive area.

If someone is struck on the left side of their head and is knocked unconscious and wakes unable to hear but not understand the meaning of phrases or sentences. That would imply damage to what area of the brain?

Electroencephalogram

A(n) ( ) is a printed record of the brain's electrical activity over a period of time.

Medulla oblongata

The control of the heart rate and blood pressure is based in the:

Septum Pellucidum

The thin partition that seperates the first and second ventricles is the:

Cerebral peduncles

Nerve fiber bundles on the ventrolateral surface of the mesencephalon are the:

Interventricular foramen

Each lateral ventricle communicates with the third ventricle through a(n):

Provide the general pattern and rhythm for movements such as walking

What does the basal nuclei provide?

III, IV, VI

The crainial nerves that innervate the eye muscles are:

Hypothalamus

The floor of the diencephalon is formed by the:

Lateral Sulcus

The superior border of the temporal lobe is marked by the

Integrative

( ) centers recieve information from many association areas and direct extremely complex motor activities such as speech.

Pons

The tracts that connect the cerebellum to the brain stem are located in the:

Ependymal

Specialized ( ) cells form the secretory component of the chorois plexus.

Medial; Gross; Proximal

The ( ) pathway controls ( ) movements of the trunk and ( ) limb muscles

Posterior (dorsal) column

Which ascending tract carries the sensations for fine touch and vibrations

Anterior corticospinal

The descending spinal tract that crosses the opposite side of the body within the cord is the ( ) tract.

Inner ear; eyes; proprioceptive sensations; motor commands from upper neurons

The cerebellum relies on information from what souces:

Tactile receptor

A receptor that contains mechanically gated ion channels would function best as a:

Referred pain

When pain is felt in a region other than where the injury is located. Such as left arm pn from a heart attack.

Provide the background patterns of movement in voluntary motor activities

The basal nuclei does what?

Corticospinal

The pyramids on the ventral surface of the medulla oblongata are formed by the fibers of the ( ) tracts.

If must be recieved by the somatosensory cortex

In order for a sensation to become a perception what must occur.

Baroreceptors

Mechanoreceptors that respond to changes in blood pressure are called:

Nocioceptor

A sensory receptor characterized peripherally as a free nerve ending and centrally uses glutamine and/or substance P as neurotransmitters, would most likely be.

Fast Pain

What is sometimes called "prickling pain"

Merkel; Meissner

Tactile disks are to ( ) as tactile corpuscles are to ( ).

Neither

Which part of this statement is true?
Somatic sensory axons enter the ventral root and usually ascend directly to the thalamus.

The ability to make reflex responses of the head and neck in response to sudden movements or loud noises

Damage to the tectospinal tracts would interfere with:

Baroreceptors; Chemoreceptors

Bladder fullness is to ( ) as blood pH is to ( ).

Tectospinal

The medial pathway that controls involuntary movement of the head, neck, and arm position in response to a sudden visual or auditory stimuli is the ( ) tract.

Both are true

What part of the statement is true?
If the primary motor cortex is destroyed, fine control of movement will be lost, but may not be lost completely because the medial and lateral pathways can still provide coarse motor control.

Acetylcholine; GABA

Huntington disease is caused by the destruction of the basal nuclei that use different neurotransmitters. One is ( ) and the other is ( ).

Chain

Clusters of ganglionic sympathatic neurons lying along either side of the spinal cord are called sympathatic ( ) ganglia.

Mesencephalon

Based on stimulation studies, the "headquarters" of the reticular activating system appears to be based in the:

Sympathetic chain ganglia

Postganglionic fibers that innervate targets in the body wall or thoracic cavity originate on neurons within:

Thoracolumbar division

The sympathetic division of the ANS is also known as:

Stimulating serotonin receptors

Hallucinogenic drugs, such as LSD, function by:

NO

Is celiac ganglion a parasympathetic ganglion?

Open chemically gated sodium ion channels

Nicotonic receptors do what?

Both are true

What part of this statement is true?
There is always a peripheral synapse between the CNS and the effector organ.

Parasympathatic

The ( ) division of the autonomic nervous system is said to function during "rest and digest"

NO

Is the pupillary reflex coordinated by the medulla oblongata?

Liver, spleen, pancrease, stomach

The celiag ganglia innervate what?

Slow wave

The EEG pattern in deep sleep is characterized by a:

Activates B2 receptors; blockes muscarinic receptors

An inhaler used to treat airway constriction in asthma or allergy might contain a drug that:

Digestion

The parasympathetic nervous system is especially active during which physiological state?

Both - Dual innervation

The diameter of the respiratory passages are innervated by which autonomic system?

Axons that synapse in the collateral ganglia

Splanchnic nerves consist of:

Myelinated, long; Unmylenated short

In general, parasympathetic pregangionic fibers are ( ) and postganglionic fibers are ( ).
