This tube is organized into a series of four distinct layers which are fairly consistent throughout its length. Click on a link for more detail, or scroll down. Terms such as inside and outside are potentially confusing when used to describe tubular organs.
The nerves, muscles, and joints must work together in a chain to produce motion kinetic. These three systems are also referred to as the kinetic chain. Billions of neurons make up nervous system, provides it with ability to communicate internally with itself as well as externally with environment.
Transmits impulses through both electrical and chemical signals. Forms the core of the nervous system which includes the brain, spinal cord, and peripheral ganglia.
Neurons are composed of cell body, axon, and dendrites.

The cell body of Neuron contains a nucleus, lysosomes, mitochondria, and a Golgi complex. Axon — cylendrical projection from the cell body that transmits nervous impulses to other neurons or effector sites muscles, organs. Provides communication from brain and spinal cord to other parts of the body.
Dendrites — gather information from other structures and transmit it back into the neuron. So sensory neurons transmit from muscles and organs to the CNS. Motor neurons transmit nerve impulses from CNS to muscles and organs. Interneurons transmit impulses between neurons.
Nerves of PNS are how CNS receives sensory input from sensory afferent neurons and initiates responses through motor efferent neurons. The PNS serve two main functions. They provide a connection for the nervous system to activate different effector organ, muscle sites.
Second they relay information from effector organ, muscle sites back to the brain via sensory receptors, providing constant update to the relation of the body and the environment.
The PNS consists of the somatic and autonomic nervous system. The somatic nervous system consists of the nerves that serve the outer areas of the body and skeletal muscle and are responsible for the voluntary control of movement.
So somatic is what controls your biceps and legs and whatnot. The autonomic nervious system supplies neural input to the involuntary systems of the body, like your heart.
The autonomic is divided into sympathetic and parasympathetic nervous systems.The mucosa is the inner layer of any epithelially-lined hollow organ (e.g., mouth, gut, uterus, trachea, bladder, etc.).The mucosa consists of the epithelium itself and also the supporting loose connective tissue, called lamina propria, immediately beneath the timberdesignmag.com connective tissue which supports the mucosa is called the submucosa.

Anatomy is the study of the human body while physiology, is the study of how the body functions. For example, the cardiovascular system includes the heart, veins, and blood. For example, the cardiovascular system includes the heart, veins, and blood.
