https://digitalsjournal.com/ The nervous system is a complex network of nerves and cells that transmit signals between different parts of the body. It is responsible for the control and coordination of bodily functions, and allows the body to respond to internal and external stimuli. The nervous system consists of two main parts: the central nervous system, which includes the brain and spinal cord, and the peripheral nervous system, which includes all the nerves outside the brain and spinal cord. The nervous system works closely with the endocrine system to regulate the body’s physiology .”The Anatomy and Physiology of the Nervous System” This title refers to the study of the structure and function of the nervous system.

Dendrites are specialized structures that extend from the cell body of a neuron, which receive electrical signals from other neurons. They are considered the receptive part of the neuron, and are responsible for receiving and transmitting electrical signals to the cell body. Dendrites are typically short and branch-like in shape, and are covered in small protrusions called dendritic spines, which receive signals from the synapses of other neurons. The signals that are received by the dendrites are then passed on to the cell body, where they are processed and potentially passed on to the axon, which is responsible for transmitting signals to other neurons.
Axons are specialized structures that extend from the cell body of a neuron, which transmit electrical signals to other neurons or muscle cells. They are considered the output part of the neuron. Axons are typically long and thin, often extending for long distances from the cell body. The electrical signals that are generated in the cell body are conducted down the axon to the terminal boutons, which are specialized structures located at the end of the axon. These terminal boutons release chemical neurotransmitters, which bind to receptors on the dendrites of other neurons, or on muscle cells, and transmit the electrical signal to the next neuron or muscle cell. Axons also have a protective covering, called the myelin sheath, which is a fatty insulation that surrounds the axon and helps to increase the speed and efficiency of the electrical signals.
The spinal cord is a long, cylindrical bundle of nerves that runs from the base of the brain down through the center of the vertebral column. It is a major part of the central nervous system (CNS) and serves as a relay station for signals between the brain and the rest of the body. The spinal cord is protected by the vertebrae of the spinal column, which provide a physical barrier to injury.
The spinal cord is divided into 31 segments, each of which corresponds to a pair of spinal nerves that branch off the cord and exit the spinal column through intervertebral foramina. These nerves provide the communication pathway between the spinal cord and the rest of the body, carrying information to and from the brain.
The spinal cord is responsible for reflexes, which are automatic, immediate, and stereotyped responses to certain stimuli. They occur in the spinal cord and do not involve the brain.
The spinal cord also plays a role in the regulation of muscle tone and the control of movement. Some motor neurons in the spinal cord control the movement of the body’s skeletal muscles, while others control the muscles of the internal organs.
Damage to the spinal cord can result in loss of sensation and motor function below the level of the injury. The severity of the injury depends on the level of the spinal cord affected, and the degree of the damage.
