We have talked about the central and peripheral nervous systems. We know that the peripheral nervous system relays signals to an
d from the spinal cord. But this system is divided yet again. What are the two main divisions of the peripheral nervous system? How do these systems relate to the three types of muscle?
The peripheral nervous system has - Somatic nervous system and Autonomic nervous system.
These systems control our body action by this controls all the types of muscles.
Explanation:
Somatic nervous system have - Cranial nerves and Spinal nerves
Autonomic nervous system have - Sympathetic and Parasympathetic system.
The somatic nervous system controls our voluntary and involuntary actions by cranial and spinal nerves and controls all three types of muscles such as cardiac, smooth and skeletal.
The autonomic nervous system controls the involuntary actions of our internal organs.
The sympathetic and parasympathetic system relates to all types of muscle.
The sympathetic and parasympathetic system accelerates and decelerates the heart beat respectively, by this controls the cardiac muscle.
The sympathetic and parasympathetic system stimulates and relaxes our internal organs respectively, by this controls the smooth muscles.
The sympathetic and parasympathetic system prepares our body as a whole for a action and also relaxes our whole body respectively, by this controls the skeletal muscles.
Black Boy is a memoir that was written by the author Richard Wright in which he describes in detail what it was like for him growing up in the South as well as moving to Chicago in order to start his career. In this memoir he associates the bitterness and pain he feels over being abandoned by his father with the pain he feels when he is hungry
The answer to this question would be: on the rough endoplasmic reticulum.
Digestive cell produces many enzymes which were made by protein. Endoplasmic reticulum has a role in protein synthesis. It is important to have many rough endoplasmic reticulum to accommodate the protein synthesis function so that the digestive organ can produce enough enzyme
The correct answer is letter B. the closer the star, the larger the Parallax angle. This is an illusion that is made through visual perspectives of observers of stars. A parallax can also be used to find the distance to the stars that are relatively close.
