Only skeletal and smooth muscles are part of the musculoskeletal system and only the muscles can move the body. Cardiac muscles are found in the heart and are used only to circulate blood; like the smooth muscles, these muscles are not under conscious control. Skeletal muscles are attached to bones and arranged in opposing groups around joints. [8]
There are three distinct types of muscle: skeletal muscle, cardiac or heart muscle, and smooth (non-striated) muscle. Muscles provide strength, balance, posture, movement, and heat for the body to keep warm. [3] There are more than 600 muscles in an adult male human body.
[39] [41] The female external sex organs are the vulva (labia, clitoris, and vestibule). [42] [39] The male external genitalia include the penis and scrotum that contains the testicles. The testicle is the gonad, the sex gland that produces the sperm cells. Unlike the egg cells in the female, sperm cells are produced throughout life.
Superficial anatomy of female and male human body Surface projections of the major organs of the trunk, using the vertebral column and rib cage as main reference points of superficial anatomy Surface anatomy , or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the ...
There are more than 600 skeletal muscles in the human body, making up around 40% of body weight in healthy young adults. [18] [19] [20] In Western populations, men have on average around 61% more skeletal muscle than women. [21] Most muscles occur in bilaterally-placed pairs to serve both sides of the body.
The human skeleton is not as sexually dimorphic as that of many other primate species, but subtle differences between sexes in the morphology of the skull, dentition, long bones, and pelvis exist. In general, female skeletal elements tend to be smaller and less robust than corresponding male elements within a given population.
Smooth muscle is also found in lymphatic vessels, the urinary bladder, uterus (termed uterine smooth muscle), male and female reproductive tracts, the gastrointestinal tract, the respiratory tract, the arrector pili of skin, the ciliary muscle, and the iris of the eye. The structure and function is basically the same in smooth muscle cells in ...
