Skeletal,Muscular,and Nervous Systems. by Angela Reyes on Prezi
Skeletal, Muscular, and Nervous Systems. The interaction of bones . the skeletal system. • Analyze the relationship between health promotion. The human body contains more than different muscles in three categories, all under the control of the nervous system. Striated, or skeletal, muscles, come. Each of these muscles is a discrete organ constructed of skeletal muscle tissue, blood vessels, tendons, and nerves. The skeletal system and.
Contraction of cardiac muscle is primarily controlled by an internal pacemaker, and the autonomic nervous system ANS.

It is considered an involuntary muscle control, since it is not under our conscious control. Smooth muscle, such as in the digestive system, is also controlled by the autonomic nervous system. Like heart muscle, it is not under our conscious control. The SNS is responsible for controlling voluntary body movements, such as movement of the arms and legs.
It is also responsible for receiving sensory information such as touch, hearing, and sight. The SNS contains neurons that connected with the skeletal muscles, skin, and sense organs. Neurons that control skeletal muscle and organs are called motor neurons.
The SNS carries nerve impulses from the brain to the muscle to be moved. Neurons used to receive sensory information are called sensory neurons.
A stimulus, such as touch or sound, is converted to an electrical signal by a sensory receptor and transmitted to a sensory neuron. The sensory neuron carries electrical impulses back to the CNS and the brain.
For this reason, subdivisions into "central," "peripheral," "somatic" and "autonomic," as taught in anatomy courses, exist mainly to clarify extremely complex functions.
Muscular System The human body contains more than different muscles in three categories, all under the control of the nervous system.
Striated, or skeletal, muscles, come under conscious, or voluntary, control.
Smooth, or visceral, muscles, such as those found in the digestive tract, are connected to organs and perform their work outside of voluntary control. The cardiac muscle has a single specialized function confined to the heart.Homeostatic Relationships For All Systems - Integumentary , Skeletal , Muscular, Nervous, Endocrine
On average, about 40 percent of normal body weight consists of muscle. Nervous System The nervous system consists of billions of neurons in constant touch with each other for the purpose of monitoring and regulating your internal and sensory functions.
How is the nervous system connected to the skeletal system in the human body?
The central nervous system, or CNS, includes the brain and spinal cord, and the peripheral nervous system, or PNS, includes all the nerves outside the central nervous system. The spinal cord behaves like an information superhighway, speeding signals from the brain to the PNS and vice versa. Like the muscular system, the PNS, consisting of all the roads that ultimately lead to the superhighway, has a dual function.
