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
Overseeing the postural muscles of the body and making rapid adjustments to maintain balance and equilibrium are functions of the:
The dural fold that projects into the longitudinal fissure between cerebral hemispheres is called the:
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?
A(n) ( ) is a printed record of the brain's electrical activity over a period of time.
Provide the general pattern and rhythm for movements such as walking
What does the basal nuclei provide?
( ) centers recieve information from many association areas and direct extremely complex motor activities such as speech.
Posterior (dorsal) column
Which ascending tract carries the sensations for fine touch and vibrations
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:
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?
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.
A sensory receptor characterized peripherally as a free nerve ending and centrally uses glutamine and/or substance P as neurotransmitters, would most likely be.
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:
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.
Huntington disease is caused by the destruction of the basal nuclei that use different neurotransmitters. One is ( ) and the other is ( ).
Clusters of ganglionic sympathatic neurons lying along either side of the spinal cord are called sympathatic ( ) ganglia.
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:
Both are true
What part of this statement is true?
There is always a peripheral synapse between the CNS and the effector organ.
The ( ) division of the autonomic nervous system is said to function during "rest and digest"
Activates B2 receptors; blockes muscarinic receptors
An inhaler used to treat airway constriction in asthma or allergy might contain a drug that:
Both - Dual innervation
The diameter of the respiratory passages are innervated by which autonomic system?
