Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Conscious activities are controlled by the ____ nervous system
A
somatic
B
autonomic
C
peripheral
D
central
Explanation: 

Detailed explanation-1: -The somatic nervous system provides control of skeletal muscle movement. Conscious control of movement originates in the motor cortex (both premotor and primary motor cortex). However, movement is refined and coordinated by various structures in the CNS, including extrapyramidal regions and the cerebellum.

Detailed explanation-2: -The voluntary nervous system (somatic nervous system) controls all the things that we are aware of and can consciously influence, such as moving our arms, legs and other parts of the body.

Detailed explanation-3: -The somatic nervous system is under conscious control, meaning that we can choose to move our muscles or not. For example, when we decide to pick up a book, our brain sends signals down the motor neurons to our arm muscles, telling them to contract. The somatic nervous system can also undergo unconscious activation.

Detailed explanation-4: -The somatic nervous system connects the central nervous system with the body’s muscles and skin. Its primary function is to control voluntary movements and reflex arcs, while also helping us process the senses of touch, sound, taste, and smell.
