Answer
Question 1
The prefrontal cortex is associated with
a) Working memory
Question 2
The ______ delivers messages from the sensory organs to the central nervous system. options:
d) Somatic
Question 3
The _______ is part of the nervous system that is associated with the "flight or fight" response.
a) Sympathetic
Question 4
Plasticity is the brain's limited ability to change its anatomy over time.
False
Question 5
The nerve growth factor promotes the survival and growth of the axon.
True
Explanation
The prefrontal cortex is associated with
a) Working memory
Prefrontal cortex is mainly involved in working memory. The single neurons found within the prefrontal cortex helps to maintain representations of task-relevant stimuli in the working memory.
Question 2
The ______ delivers messages from the sensory organs to the central nervous system. options:
d) Somatic
The peripheral nervous system is divided into two parts, the autonomic nervous system and the sensory-somatic nervous system. The sensory-somatic branch carries messages from the sense organs and internal organs and into the central nervous system.
Question 3
The _______ is part of the nervous system that is associated with the "flight or fight" response.
a) Sympathetic
The autonomic nervous system is divided into two branches; the sympathetic nervous system and the parasympathetic nervous system. The sympathetic nervous system mediates all actions that involve fight-or-flight response like increasing the heart rate.
Question 4
Plasticity is the brain's limited ability to change its anatomy over time.
False
Brain plasticity refers to the unlimited ability of the brain to change and adapt as a result of experience. Functional plasticity is the ability of the brain to move functions from a damaged region of the brain to other undamaged region, and structural plasticity refers to the change in brain's structure as a result of learning.
Question 5
The nerve growth factor promotes the survival and growth of the axon.
True
The nerve growth factor is a polypeptide that regulates the growth and differentiation of the sympathetic and certain sensory neurons. It is specifically essential in the survival of sympathetic neurons in a culture.
