Human Nervous System
The human nervous system is a complex network of cells and tissues that carry messages between the brain and the rest of the body. The nervous system is divided into two parts: the central nervous system and the peripheral nervous system.
The central nervous system consists of the brain and spinal cord. The brain is the control center of the body, and the spinal cord is a long, thin bundle of nerves that runs down the back. The peripheral nervous system consists of the nerves that run from the central nervous system to the rest of the body.
The nervous system carries messages between the brain and the rest of the body by means of electrical signals. These signals are transmitted along the nerves in the form of tiny electrical impulses. When these impulses reach a muscle or other tissue, they cause the tissue to contract or relax.
What is the Axon?
The Axon is a nerve fiber that carries information away from the cell body of a neuron. It is a long, thin, cylindrical structure that is covered in a myelin sheath, which helps to speed the transmission of nerve impulses. The axon is typically the longest part of a neuron, and can be up to 1 meter long in some cases.
The Difference Between Axon and Dendrite
Axon and dendrite are two important structures of a neuron. Axon is the long, slender projection of a neuron that carries nerve impulses away from the neuron’s cell body. Dendrite is the short, branching projection of a neuron that receives nerve impulses from other neurons.
The main difference between axon and dendrite is that axon carries nerve impulses away from the neuron’s cell body, while dendrite receives nerve impulses from other neurons.
Axons and dendrites are two important parts of a neuron. An axon is a long, thin fiber that carries signals away from the neuron’s cell body. A dendrite is a shorter, branch-like fiber that carries signals toward the neuron’s cell body.
Axons and dendrites are covered in small, hairlike projections called dendritic spines. These spines help to increase the surface area of the neuron and improve the neuron’s ability to send and receive signals.
The size, shape, and number of dendritic spines on a neuron can vary from neuron to neuron. This can affect the strength and speed of the neuron’s signals.
