Explanation:

• Skeletal - Muscular Link: Muscles (like skeletal muscles) attach to bones via tendons. When muscles contract, they pull on bones, enabling movement (e.g., biceps pulling on the radius to flex the arm). Bones also provide a structure for muscles to anchor to, allowing force generation for motion.
• Skeletal - Nervous Link: Bones protect parts of the nervous system. For example, the skull protects the brain (central nervous system), and the vertebrae protect the spinal cord. Also, sensory receptors in bones (e.g., for proprioception) send signals to the nervous system about body position.
• Muscular - Nervous Link: The nervous system (via motor neurons) controls muscle contraction. Motor neurons from the brain/spinal cord send electrical signals to muscle fibers, triggering contraction. Conversely, muscles have sensory receptors (like muscle spindles) that send feedback to the nervous system about muscle length/tension, aiding in coordination and reflexes.

Answer:

• Skeletal - Muscular Link: Skeletal muscles attach to bones via tendons; muscle contraction pulls bones to produce movement (e.g., biceps flexing the arm), and bones act as levers/anchors for muscle force.
• Skeletal - Nervous Link: Bones (skull, vertebrae) protect the brain/spinal cord (nervous system). Sensory receptors in bones also send position - related signals to the nervous system.
• Muscular - Nervous Link: The nervous system (motor neurons) controls muscle contraction (e.g., motor neurons trigger muscle fiber activation). Muscles have sensory receptors (e.g., muscle spindles) that send feedback to the nervous system about muscle state for coordination.
