How is the automatic nervous system divided?
When we speak of the autonomic nervous system we are really talking about three main main divisions: sympathetic, parasympathetic, and enteric
Peripheral System is a division of the Nervous System. They have 2 types of cells. The sensory nervous cells carry information to the central nervous system; and the motor nervous cells carry information from the central nervous system. The Peripheral System is also divided into the somatic nervous system (controls the voluntary muscles) and the automatic nervous system (controls involuntary muscles).
The two main division of The Nervous System is divided into: Peripheral Nervous System Central Nervous System The Peripheral Nervous System is divided into two major parts:The somatic nervous system and the autonomic nervous system. While The Central Nervous System is divided into two parts: the brain and the spinal cord.
Grossly, the nervous system is divided into the central nervous system that includes the brain and the spinal cord; and the peripheral nervous system that includes the cranial nerves and the spinal nerves. Physiologically, the nervous system is divided into the somatic nervous system and the autonomic nervous system that is divided into sympathetic and parasympathetic divisions. Peripheral and Central Nervous System.
The nervous system includes the brain, the spinal cord, nerves which go to and from the spinal cord, nerves which come from sensory structures like the eye, ear, touch receptors, etc, nerves which go to muscles, as well as neurons which are present in the stomach and intestines which function like a mini-brain. The nervous system is divided into the Central Nervous System (CNS: brain and spinal cord), and the Peripheral Nervous System (PNS: nerves…
