The nervous system is the organ responsible for carrying out the unity between the body and the outside environment. Coordinates all activities of the organ and the environment inside the body.

The nervous system is the organ responsible for carrying out the unity between the body and the outside environment. Coordinates all activities of the organ and the environment inside the body.

In terms of anatomy, the nervous system is divided into two parts:

Central nervous system: brain and spinal cord.

Peripheral nervous system: includes 31 spinal nerves, 12 cranial nerves and corresponding nerve nodes: sympathetic ganglion, spiny ganglia ...

Physiologically divided into two systems:

Animal nervous system: controls striated muscles and sensory receptors.

Nervous system: motor centrifugal fibres control smooth muscle, heart muscle, sweat gland.

In terms of the embryonic nervous system arises from the epidermis. The epidermis flexes and closes the neural tube wall with features:

The first part consists of three brains.

The anterior cerebral cortex develops into the brain and brain.

The middle cerebral sac becomes the central brain

The posterior cerebral sac develops into cerebral fillings, including brain stem and cerebral pitting

The tail is the spinal cord that develops into the spinal cord when it is mature.
