The Nervous System Organization
The nervous system is composed of the central nervous system and the peripheral nervous systems. The central nervous system, which is includes the brain and the spinal cord, processes and coordinates all incoming sensory information and outgoing motor commands, and it is also the seat of complex brain functions such as memory, intelligence, learning, and emotion. The peripheral nervous system includes all neural tissue outisde of the central nervous system. It is responsible for providing sensory, or afferent, information to the central nervous system and carrying motor, efferent, commands out of the body's tissues. Voluntary motor commands, such as moving muscles to walk or talk, are controlled by the somatic nervous system, while involuntary motor commands, such as digestion and the heart, are controlled by the autonomic nervous system. The autonomic nervous system is further divided into two systems. The sympathetic nervous system, sometimes called the "fight or flight" system, increases alertness, stimulates tissue, and prepares the body for quick responses to unusual situations. In contrast, the parasympathetic nervous system, somestimes called the "rest and response" system, conserves energy and controls sedentary activities, such as digestion.

What Makes Up a Muscle
Typical Joint & Muscle Movement
This bicep muscle is attached to the bone via tendons. The bones, seated on cartilage, rotate about the joint and are held into place by ligaments.
The bones move through a joint rotation. This bicep muscle, when the muscle filiments contract, move the lower arm inward. When the muscle filiments elongate (relax), the lower arm moves outward.
Typical Joint & Muscle
Limbs move in a controlled manor through tension. In this example, in order for the bicep to contract and move the arm from the elbow to the hand inward, the tricep muscle relaxes (elongates). This allows the bicep muscle to contract and move the arm about the joint. If however the tricep and bicep muscles would contract at the same time, the lower arm would not move. Meaning, both muscles would be trying to move the arm in opposite directions at the same time. Impossible. Result would most likely be a muscle cramp.
Joints Have Specific Purposes

The Spine and How You Load The Spine Determines Its Effectiveness
When muscle fibers contract, hair-like filiments are pulled inward and onto each other. The pulling hair-like attraction process is activated by calcium and other elements. The contraction process takes place within the I-Band. The M-Band are where the filiments rest (outward) when not being contracted inward. The Z-Line separates and acts as a partition.
Muscles of The Lower Leg
Specific joint types for different movement allow our bones to move in specific directions.
