Which of the following is NOT part of the peripheral nervous system?
Ksju [112]

The correct answer is: B. spinal cord  

The nervous system can be divided into two subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS). The spinal cord and the brain are part of the CNS, whereas the PNS consists of the nerves that radiate from the CNS to all parts of the body. The PNS includes all neurons that sense and transmit information to the CNS.

The CNS controls thinking processes, movements, and registers the sensations throughout our body. Moreover, the PNS acts to transmit information from the CNS to all parts of the body.

The PNS is in turn divided into two main parts:

1-The Autonomic nervous system (ANS), which regulates involuntary functions and glands. The parasympathetic nervous system is one division of the ANS that controls visceral organs such as glands.

2- Somatic nervous system (SNS), which regulates voluntary muscle movement and transmits information from eyes, ears, and skin to the CNS.

How would you describe the relationship that gravity has with mass and distance.
PSYCHO15rus [73]

Answer:

Mass does not affect gravity and distance has an indirect relationship.

Explanation:

The equation for gravity is, g = \frac{GM}{R^{2} }

where, G = gravitational constant

             M = mass of the planet

             R = distance between the bodies (object and center of planet)

so, gravity depends on the mass of planet,  not on mass of object

 and is inversely proportional to sqaure of distance.
