Exam 17: Pathways and Integrative Functions

This pathway conducts sensory stimuli concerned with proprioceptive information about limb position and discriminative touch,precise pressure,and vibration sensations.It projects through the spinal cord,brainstem,and diencephalon before terminating within the cerebral cortex.

-This figure shows the anterolateral pathway.What structure does number 4 indicate?

Mental processes such as awareness,knowledge,memory,perception,and thinking are collectively called

Which is a deep and profound state of unconsciousness from which a person cannot be aroused?

Immediately posterior to the Wernicke area is the angular gyrus.What does this gyrus do?

In general,left-handed people have a ________________,which suggests that more signals may be relayed between their hemispheres.

Complex unconscious motor patterns are controlled by neurons in various locations.The ones that control swinging the arms while walking are located in the

Which is not a somatosensory pathway?

The inability to either recognize or understand the meaning of various stimuli is termed

Which type of memory is required to perform several different mental activities simultaneously?

A cerebrovascular accident (stroke)is caused by an increase in blood supply to a part of the brain due to a blocked or damaged arterial blood vessel.

Which of these movements or muscle groups is not controlled by motor information transmitted by the corticobulbar tracts?

Brain growth is 95 percent complete by the age of

Following birth,the CNS continues to mature and gain in complexity.As it matures many neurons expand their number of connections.

The effects of aging on the brain begin at about ________ of age.

The Wernicke area is responsible for

Which is a form of impaired memory processing that occurs following years of alcohol abuse?

This pathway conducts proprioceptive information to the cerebellum for processing to coordinate body movements such as posture,balance,and skilled movements.

Of the four indirect motor spinal cord pathways that originate in the brainstem,the one whose upper motor neuron destination is the lateral funiculus is the

The corticobulbar tracts originate from the ______ region of the motor homunculus within the primary cortex.
