The list below describes such skeletal movements as normally are possible in particular joints of the human body. Other animals have different degrees of movement at their respective joints; this is because of differences in positions of muscles and because structures peculiar to the bodies of humans and other species block motions unsuited to ...
spinous process, occipital bone, area between superior nuchal line and inferior nuchal line: greater occipital nerve: extends head: 2 1 multifidus lumborum Torso, Back, right/left sacrum, erector spinae aponeurosis, PSIS, and iliac crest: spinous process: posterior branch of spinal nerve: stabilizes vertebrae in local movements of vertebral ...
The skeletal system serves many important functions; it provides the shape and form for the body, support and protection, allows bodily movement, produces blood for the body, and stores minerals. [4] The number of bones in the human skeletal system is a controversial topic.
The muscular system is an organ system consisting of skeletal, smooth, and cardiac muscle. It permits movement of the body, maintains posture, and circulates blood throughout the body. [1] The muscular systems in vertebrates are controlled through the nervous system although some muscles (such as the cardiac muscle) can be completely autonomous.
Examples include a movement of the knee, where the lower leg changes angle compared to the femur, or movements of the ankle. [2] The study of movement in the human body is known as kinesiology. [4] A categoric list of movements and the muscles involved can be found at list of movements of the human body.
However, eye movements (particularly saccades used on facial scanning and reading) do require high speed movements, and eye muscles are exercised nightly during rapid eye movement sleep. The statement that "the tongue is the strongest muscle in the body" appears frequently in lists of surprising facts, but it is difficult to find any definition ...

Movement is powered by skeletal muscles, which are attached to the skeleton at various sites on bones. Muscles, bones, and joints provide the principal mechanics for movement, all coordinated by the nervous system. It is believed that the reduction of human bone density in prehistoric times reduced the agility and dexterity of human movement.
