Brachioradialis muscle Latissimus dorsi muscle Gluteus maximus muscle Gastrocnemius muscle Tibialis anterior Peroneus longus muscle Pectoralis major muscle Rectus abdominis muscle Rectus femoris muscle

Determine the primary function of the following system components. Function- What is the type of muscle movement involved with each muscle? Muscle of the neck that bends the head toward the sternum and turns the head to either side. Muscle of the shoulder that raises the shoulder pulls the shoulder blades together and elevates the clavicle. Turns the head side to side and moves the head posteriorly. Muscle of the chest that moves the arm interiorly and medially across the chest. Muscle in the shoulder that raises and lowers the arm and moves the arm away from the body. Muscle of the upper arm that bends the upper arm toward the shoulder and bends the lower arm toward the upper arm. One end is divides into two heads. Muscle of the upper leg that bends the upper leg toward the abdomen and straightens the lower leg. Muscle in the lower leg that bends the foot up toward the leg. Muscle in the lower leg that bends the foot downward.

Determine the primary function of the following system components. Structure Function- What is the purpose of the body part? Toughest, outermost layer of the meninges. Lies just beneath the bones of the cranium and within the foramen of each vertabra. .Thin, delicate innermost layer of the meninges. It covers the surface of the brain and contains many small blood vessels. Small, rounded structure that is the most posterior part of the brain. Monitors muscle tone and position and coordinates new muscle movements. Thick white band of nerves that connects to the two hemispheres of the cerebrum and allows them to communicate and coordinate their activities. Lobe of cerebrum that predicts future events and consequences. Exerts conscious control over the skeletal muscles. Most inferior part of the brainstem that joins to the spinal cord. It relays nerve impulses from the cerebrum to the cerebellum . It contains the respiratory center. Area of the brainstem that relays nerve impulses from the body to the cerebellum and back to the body. Area where nerve tracts cross from one side of the body to the opposite side of the cerebrum. Cranial nerves originate there. Lobe of the cerebrum that receives and analyzes sensory information from the eyes. Contains the visual cortex for the sense of light. Lobe of the cerebrum that receives and analyzes sensory information about temperature, touch, pressure, vibration, and pain from the skin and internal organs.
