A skeletal muscle response is primarily triggered by the activation of motor neurons, which release the neurotransmitter acetylcholine at the neuromuscular junction. This binding initiates an action potential in the muscle fiber, leading to the release of calcium ions from the sarcoplasmic reticulum. The increase in calcium concentration enables the interaction between actin and myosin filaments, resulting in muscle contraction. Thus, the coordinated actions of the nervous system and muscle fibers cause skeletal muscle responses.
Yes, the effector of a skeletal muscle is part of a somatic reflex. Somatic reflexes involve the contraction of skeletal muscles in response to a stimulus, and the effector in this case is the skeletal muscle itself that carries out the response.
Striated (or skeletal) muscle
Skeletal or voluntary muscle is capable of rapid contraction and is responsible for skeletal movement.
It is the variation of stimulation needed in skeletal muscle contraction in order to have controlled movement.
Smooth muscle, skeletal muscle, and cardiac muscle all contract in response to signals from the nervous system or hormones. However, the contraction mechanism of smooth muscle is different from that of skeletal and cardiac muscle. Smooth muscle contracts more slowly and can sustain contractions for longer periods of time compared to skeletal and cardiac muscle. Additionally, smooth muscle does not have striations like skeletal and cardiac muscle, which gives it a more uniform appearance.
