Detailed explanation-1: -Neurons carry messages from the brain via the spinal cord. These messages are carried to the muscles which tell the muscle fibre to contract, which makes the muscles move.
Detailed explanation-2: -The brainstem controls movement of the eyes, face, and mouth. It also relays sensory messages (such as hot, pain, and loud) and controls respirations, consciousness, cardiac function, involuntary muscle movements, sneezing, coughing, vomiting, and swallowing.
Detailed explanation-3: -Answer and Explanation: The statement that is false is d. sarcomeres increase in length during contraction. Sarcomeres are the smallest contractile units of muscles and they actually shorten, which causes muscle contraction.
