lactic acid
Effectors are located throughout the body in organs and tissues. They are responsible for producing responses to stimuli from the nervous system, such as muscles contracting or glands secreting hormones. Effector organs include muscles, glands, and other specialized tissues that carry out the body's responses to maintain homeostasis.
Muscles are capable of contracting in the human body. This allows movement, support of body structures, and distribution of substances throughout the body.
Muscles allow the body to move by stretching and contracting. When a muscle stretches, it lengthens, and when it contracts, it shortens. This movement is controlled by signals from the brain through the nervous system.
Shivering is a physiological response to cold temperatures that helps generate heat by rapidly contracting and relaxing muscles. This process requires energy, which is produced through the contraction of muscles, leading to the generation of heat to help maintain body temperature.
The muscular system produces movement by contracting and relaxing muscles, while the skeletal system provides structure and support for the body. Together, these systems work in tandem to allow for mobility and maintain the body's form.
Muscle cells produce lactic acid during anaerobic fermentation. A buildup of lactic acid cause your muscles to feel tired.
A muscle is either contracting (doing work) or relaxing (not under tension). Some muscles do not ever completely relax under normal conditions.
Relax. Muscles can only work by contracting (tensing). When an opposite force is desired, an opposite muscle contracts.

When your quadriceps bulge out, these muscles are likely contracting. Contraction of the quadriceps muscles results in a bulging appearance due to increased tension and activation of the muscle fibers.
Diaphragm and intercostals
The answer is "True"
The extensor back muscles help to keep the spine upright and stable by contracting to extend the spine and maintain proper posture. They provide support and strength to the spine, helping to prevent slouching and maintain a healthy alignment.
