Final answer:
The somatic nervous system controls voluntary movements and functions in the body. It innervates muscles, skin, tendons, and indirectly controls the muscles attached to bones.
Step-by-step explanation:
The somatic nervous system (SNS) is responsible for controlling voluntary movements and functions in the body. It consists of the spinal nerves and cranial nerves that connect directly to the brain. Here are four tissues that are innervated by the somatic nervous system:
- Muscles: The somatic nervous system controls skeletal muscles, which allow us to move our bodies voluntarily. For example, when you lift your arm or walk, your somatic nervous system is involved.
- Skin: The somatic nervous system innervates the sensory receptors in the skin, allowing us to feel touch, pressure, temperature, and pain.
- Tendons: Tendons are connective tissues that connect muscle to bone. The somatic nervous system controls the muscle contractions that occur through the tendons, allowing us to perform movements like grabbing and gripping objects.
- Bones: While bones themselves do not have direct innervation, the somatic nervous system controls the muscles attached to bones. These muscles enable movements and provide stability to the skeletal system.
