The Nervous system consists of the following three parts:
1.Brain
2.Spinal Cord
3.Neurons
the brain, spinal cord and peripheral nerves
The basic neuroanatomical structure consists of the brain and spinal cord, which make up the central nervous system (CNS), and the peripheral nerves that extend throughout the body. The CNS is responsible for processing and transmitting information, while the peripheral nerves carry sensory and motor signals between the CNS and the rest of the body.
The nervous system is used to trasmit information around the body. It is made of two systems: the central nervous system (which consists of the spine and brain) and the peripheral nervous system (which consists of neurones and receptors). There are three types of neurones: sensory neurones, relay neurons, and motor neurones.
In humans, the nervous system performs the following functions: note: a small basic list is provided. In reality, the nervous system is capable of doing much more The central nervous system: * controls the beating of the heart * is in control of peristaltic movements * is in control of bowel movemets * is in control of reflexes The peripheral nervous system: controls all voulentary muscles in the body
Nervous tissue is one of the four basic building block tissues in the human body (epithelial, connective and muscle tissue being the other three). Nervous tissue exists either as part of the central nervous system (CNS; brain and spinal cord) or the peripheral nervous system (PNS; cranial and peripheral nerves and ganglia). I assume this is what your question refers to.
The basic components of the ANS are the sympathetic and parasympathetic branches. The sympathetic branch, or SNS, is responsible for the flight-or-fight response and the parasympathetic, or PNS, is called the rest-and-digest system.parasympathethic and sympathetic nervous system
Amphibians have a relatively simple nervous system compared to mammals and birds. They possess a central nervous system composed of a brain and spinal cord, as well as peripheral nerves that transmit information throughout the body. Their nervous system allows for basic behaviors such as movement, feeding, and responses to environmental stimuli.
The basic components of the excretory system are: kidneys urethra bladder ureters
The nervous system is broken into the central and autonomic nervous systems. The central nervous system consists of the brain and spinal cord. The autonomic nervous system contains the peripheral nerves.
neuron
Neurons are the basic structural unit of nervous system.But there are other cells called as neuroglial cells (comprise 50% of the total nervous system along with nerve cells) which are also the structural unit of nervous system.Neurons on the other hand are functional unit too but neuroglial cells are not.
Nerve cells are the basic functioning component in the nervous part of the system whether peripheral or central is comprised of neurons that collect and distribute information to make the body function.
