The nervous system is one of the body’s complex functions that contain a network of cells and nerves that transmit signals from the brain and spinal cord to different areas of the body. It is categorized into two groups; the central nervous system which is made up of the brain and spinal cord, and the peripheral nervous system which contains the body’s nervous tissue and is where neurologic responses occur. Homeostasis, which is the process in which thermoregulation is maintained, also happens in this area.
The Central nervous systems include the brain and spinal cord which transfers voluntary nerve impulse to skeletal muscles, skin, muscles, and glands.
The cortex, also called gray matter, is the most external layer of the brain and predominantly contains neuronal bodies (the part of the neurons where the DNA-containing cell nucleus is located). The gray matter participates actively in the storage and processing of information. An isolated clump of nerve cell bodies in the gray matter is termed a nucleus (to be differentiated from a cell nucleus). The cells in the gray matter extend their projections, called axons, to other areas of the brain.
There are two major subdivision of the nervous system, the Central nervous system (CNS) which consist of the brain and the spinal cord and the Peripheral nervous system(PNS) consisting of the neutral tissues outside the brain and the spinal cord. The Central Nervous System integrates and coordinates all bodily functions, process all incoming messages and send commands to different body parts. Sending and receiving messages through the spinal cord and the part of the spinal column called a trunk line, which contains neurons that connect to the Peripheral Nervous System. The Peripheral Nervous System provides the Central Nervous System with information from sensory receptors, relays messages from the brain to the body's organs and muscles.
* White matter is one of the two components of the central nervous system, and it consists of glial cells and myelinated axons that transmit signals from one region of the cerebrum to another as well as in between the cerebrum and lower brain centers. Grey matter contains neural cell bodies. Unlike white matter, it is mostly made up of myelinated axon tracts. Tracts are bundles of fibers that connect to different parts of the CNS. Roots receive information sent by neurons. Spinal nerves refer to a mixture of spinal nerves, which carry
Our nervous system is there to help to transfer the things our body feels and what we need. The nervous is broken up into two parts, the central nervous system (CNS), and the peripheral nervous system (PNS). The CNS controls the brain and the spinal cord, the PNS controls the nerves and the ganglia (a small mass of gray matter). Our body uses the spinal cord to send messages to the nerves so that it can control our organs and muscles.
The central nervous system consists of the brain and spinal cord. The brain takes information from the senses and processes it and it also makes decision sand sends commands to the body. The spinal cord carries information to and from away the brain. The peripheral system, on the other hand, is the system that allows communication between the central nervous system with the sensory systems. It also makes it possible for the brain and spinal cord to control muscles and
The nervous system is a multiplexed body system that controls most other body systems directly or indirectly by sending and receiving signals through a complex system of nerves. As a whole, the nervous system can be broken down into the central nervous system (CNS) and peripheral nervous system (PNS). The CNS is composed of the brain and spinal cord while the PNS is composed of peripheral nerves that branch off of the spinal cord and continue to branch to reach the most distal points of the limbs. The PNS can be further broken down into the afferent and efferent division. The afferent division deals with information brought to the CNS from the nerve receptors. Furthermore, the afferent division breaks down into somatic sensory receptors whose
The nervous system is split up into two main organizations, the central nervous system (CNS) and the peripheral nervous system.
There are two main divisions that comprise the nervous system: the central nervous system consisting of the brain and the spinal cord and the peripheral nervous system consisting of somatic and autonomic nervous systems (Kalat, 2013). The brain and the spinal cord make up the central nervous system and is responsible for the transmission of nervous impulses as well as receiving sensory information (Siegal, 1999). The peripheral nervous system, consisting of cranial nerves, spinal nerves, and peripheral ganglia, is responsible for transmitting information to the central nervous system as well as the rest of the body (Hubbard, 2013).
All portions of the nervous system outside the brain and spinal cord; it includes sensory and motor nerves
The anatomical and functional divisions of the nervous system are divided into two categories the central nervous system (CNS) and the peripheral nervous system (PNS).
The central nervous system (CNS) consists of the brain and spinal cord. It sends information to (and receives information from) the peripheral nervous system (PNS), which consists of all of the nerves that lie outside the CNS. The PNS collects information about the environment, sends it to the CNS and transports output from the CNS to
The human nervous system is divided into two parts, the central nervous system and the peripheral nervous system. The central nervous system, CNS, is just the brain and spinal cord. The peripheral nervous system, PNS, includes the nerves and neurons that extend outwards from CNS, to transmit information to your limbs and organs for example. Communication between your cells is extremely important, neurons are the messengers that relay information to and from your brain.
The nervous system is divided into two major sections: There is the central nervous system and the peripheral nervous system.
