which of the following is a function of the skeletal system beyond providing structural support?
a. protecting vital organs
b. regulating blood pressure
c. producing hormones
d. digesting food
which system works closely with the musculoskeletal system to facilitate movement?
a. digestive system
b. endocrine system
c. nervous system
d. respiratory system

Explanation:

1. Long bones (e.g., femur, humerus) act as levers for muscles, enabling movement, and provide structural support for the body.
2. Tendons are fibrous tissues that link skeletal muscles to bones, while ligaments connect bone to bone to stabilize joints.
3. Ligaments are specialized connective tissues that anchor bones together at joints to maintain stability and guide movement.
4. Hematopoiesis is the process of forming new blood cells (red blood cells, white blood cells, platelets) which occurs in the red bone marrow of bones.
5. Beyond structural support, the skeletal system encloses and protects vital organs (e.g., skull protects the brain, ribcage protects the heart and lungs).
6. The nervous system sends signals to skeletal muscles, which contract and pull on bones to initiate movement, working closely with the musculoskeletal system.

Answer:

1. b. Aiding in movement and support
2. b. Tendons attach muscles to bones, and ligaments connect bones to other bones.
3. d. Connect bones to other bones at joints
4. c. The production of blood cells in bone marrow
5. a. Protecting vital organs
6. c. Nervous system
