Inside the brain and spinal cord are neurons and neuroglia.
The brain is in your head and the spinal cord runs through the vertebrae (the bones that make up your neck and spine)
Central nervous system
The central nervous system is the brain and spinal cord. It s located in the cranial cavity (brain) and the spine (spinal cord).
The spinal cord is attached to the brain stem located at the base of the brain. This stem is connected to the cerebellum.
The brain is superior to the spinal cord.
Neurons are the messengers of the central nervous system (CNS) which is composed of the brain and the spinal cord.
a tract is a bundle or group of nerve fibers located within the brain or spinal cord
There is no joint between brain and spinal cord. The spinal cord is a mass of neurones that is situated in the backbone which feeds in to the brain via neurones.
The brain stem connects the brain to the spinal cord, so that the brain can send messages through the cord to the rest of the body. The functioning of the body is severely compromised if the spinal cord connections are severed.
Membranes called meninges cover and protect the brain and spinal cord. The skull and spinal column also protect the brain and spinal cord, respectively. The spinal cord is made up by individual vertebrae.
Nerves
The spinal cord is located in the central nervous system along with the brain. Whilst the nerves connecting the spinal cord to the body are reffered to as Peripheral Nervous System. Alex and Amelia :-)
it is a colourless, hydraulic cushion found within the ventricles of the brain, subarachnoid space around brain and spinal cord. functions: it acts as a shock absorber to protect the brain and spinal cord. it supplies nutrition to the brain and spinal cord. it removes waste products from the brain and spinal cord. it protects the brain and spinal cord from diseases causing organisms.
most of the neurons in the brain and spinal cord are
