Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Humans feel hungry when their empty stomachs contract and glucose levels in their body drop. Both of the situations stimulate neurons that send messages to the brain which are interpreted as hunger. What body systems are involved in this process as described?
A
digestive, muscular, integumentary, and respiratory
B
digestive, excretory, integumentary, and skeletal
C
circulatory, excretory, nervous, and skeletal
D
circulatory, digestive, muscular, and nervous
Explanation: 

Detailed explanation-1: -The spinal cord, basically a highway for nerves, streamlines sensory and motor signals to the brain and the body. Information detected by sensory receptors in the periphery is transmitted along ascending neural tracts in the spinal cord.

Detailed explanation-2: -The spinal cord runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part. This network of nerves relays messages back and forth from the brain to different parts of the body.

Detailed explanation-3: -The brain is a complex organ that controls thought, memory, emotion, touch, motor skills, vision, breathing, temperature, hunger and every process that regulates our body. Together, the brain and spinal cord that extends from it make up the central nervous system, or CNS.

Detailed explanation-4: -The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
