What is the Parasympathetic Nervous System? The parasympathetic nervous system (PNS) is one of the two main branches of the autonomic nervous system, the other being the sympathetic nervous system. Together, these systems regulate involuntary bodily functions, including those related to the heart, lu...
Parts of the Nervous System The vertebrate nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain, spinal cord, and retina—the sensory tissue of the visual system. The PNS contains the sensory rece...
There are two main parts of the nervous system, the central nervous system (CNS), which consists of the brain and spinal cord, and the peripheral nervous system (PNS) which are all the numerous nerves that connect the central nervous system to the rest of the body. The nerves which transm...
The nervous system has two primary components: the central nervous system (CNS) and the peripheral nervous system (PNS).Answer and Explanation: The CNS consists of the brain and the spinal cord. The PNS is composed of the sensory and motor neural tissue outside of...
When sleeping, the parasympathetic nervous system is most highly active. It controls all the basic functions of sleep and allows the mind to drift into an unconscious state of rest and renewal for the conscious mind. The brain never turns off, but is always working at the unconscious level. ...
Peripheral Nervous System (PNS) The peripheral nervous system is everything connected to the central nervous system. It has motor nerves, sensory nerves, and autonomic nerves. Autonomic nerves act automatically, which is a way to remember them. They are the nerves that regulate our bodies. They...
Step-by-Step Solution:1. Definition of Nervous Tissue: - Nervous tissue is a specialized type of tissue in the body that is primarily responsible for transmitting nerve impulses. It consists mainly of two t
There are three basic structures of the Nervous System. First, is the Central Nervous System, otherwise known as (CNS). This consists of the brain and spinal cord. Second is the Peripheral Nervous System, otherwise known as (PNS). This consists of all the nerves outside of the brain and...
What are the main parts of Peripheral Nervous System (PNS)? What are the main parts of central nervous system? A collection of neuron cell bodies outside of the CNS is called a ___. What is the pathway of an axon of a somatic motor neuron?
other reasons, it is thought to represent an extension of the central nervous system apparatus that controls vision. In fact, doctors can diagnose inflammation of the head of the optic nerve by using an ophthalmoscope, as if the person's eyes were a window into the central nervous system. ...
