Receptors in muscles provide the brain with information about body position and movement. The brain controls the contraction of skeletal muscle. The nervous system regulates the speed at which food moves through the digestive tract.
What is the nervous system connected by?
Think of the brain as a central computer that controls all the body’s functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back.
What does the muscular system do?
The muscular system is composed of specialized cells called muscle fibers. Their predominant function is contractibility. Muscles, attached to bones or internal organs and blood vessels, are responsible for movement. Nearly all movement in the body is the result of muscle contraction.
What is the study of cells in the nervous system called?
Neuroscience is the scientific study of the nervous system (the brain, spinal cord, and peripheral nervous system) and its functions.
Are small phagocytic cells in the central nervous system?
Microglia, which constitute 10∼20 % of glia cells, are the resident macrophages of the brain and spinal cord and act as the main immune defense in the central nervous system (CNS). … Microglia are inactive under physiological conditions, with small cell body and highly ramified branching processes.
How does the muscular system work with the nervous system?
Your nervous system (brain and nerves) sends a message to activate your skeletal (voluntary) muscles. Your muscle fibers contract (tense up) in response to the message. When the muscle activates or bunches up, it pulls on the tendon.
