Question 1

Somatic System

Answer 1

Division of the peripheral nervous system (PNS) that controls voluntary motor behavior; carries motor commands from the central nervous system (CNS) to activate effector organs (ex. Muscles) in the PNS

Question 2

Autonomic nervous system

Answer 2

Division of the PNS that regulates visceral and bodily processes at the subconscious level (involuntary system) including heart rate, ventilation, digestion, and other systems involving smooth muscle and glands

Question 3

Interneurons

Answer 3

o Neurons that interconnect among other neurons; interneurons lie between motor and sensory neurons to link the sensory and motor divisions of the PNS

Question 4

Executive function

Answer 4

o A set of cognitive processes that are necessary for the cognitive control of behavior

Question 5

Multi-modal Sensory Input

Answer 5

o The convergence of incoming sensory signals into the CNS arriving from multiple sensory sources

Question 6

Sensorimotor Integration

Answer 6

o A process involving the convergence and processing of sensory information and motor commands; may involve the use of motor commands and movements to enhance sensory information and the coupling and relationship between incoming sensory information and outgoing motor actions

Question 7

Neuroplasticity

Answer 7

o is the ability of the brain to change throughout an individual’s life, e.g., brain activity associated with a given function can be transferred to a different location, the proportion of grey matter can change, and synapses may strengthen or weaken over time
