In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along the ventral surface of the femoral shaft referred to as the adductor crest. The neck of the femur is generally minimal or absent in the most primitive forms, reflecting a simple attachment to the ...
This tissue provides additional support to the pelvic floor. The endopelvic fascia is one continuous sheet of tissue and varies in thickness. It permits some shifting of the pelvic structures. The fascia contains elastic collagen fibers in a 'mesh-like' structure. The fascia also contains fibroblasts, smooth muscle, and vascular vessels.
The muscle which can 'cancel' or to some degree reverse the action of the muscle. Muscle synergies are noted in parentheses when relevant. O (Occurrences) Number of times that the named muscle row occurs in a standard human body. Here it may also be denoted when a given muscles only occurs in a male or a female body.
Female pelvic muscles Male pelvic muscles. The pelvic floor or pelvic diaphragm is an anatomical location in the human body, [1] which has an important role in urinary and anal continence, sexual function and support of the pelvic organs. [2] The pelvic floor includes muscles, both skeletal and smooth, ligaments and fascia.
Above, the linea aspera is prolonged by three ridges. The lateral ridge is very rough, and runs almost vertically upward to the base of the greater trochanter.It is termed the gluteal tuberosity, and gives attachment to part of the gluteus maximus: its upper part is often elongated into a roughened crest, on which a more or less well-marked, rounded tubercle, the third trochanter, is ...
This is covered by a membrane of connective tissue called the periosteum. Beneath the cortical bone layer is a layer of spongy cancellous bone. Inside this is the medullary cavity which has an inner core of bone marrow, it contains nutrients and help in formation of cells, made up of yellow marrow in the adult and red marrow in the child.
The panniculus adiposus is the fatty layer of the subcutaneous tissues, superficial to a deeper vestigial layer of muscle, the panniculus carnosus. [1] It includes structures that are considered fascia by some sources but not by others. Some examples include the fascia of Camper and the superficial cervical fascia. [2]
The pelvic cavity also contains major arteries, veins, muscles, and nerves. These structures coexist in a crowded space, and disorders of one pelvic component may impact upon another; for example, constipation may overload the rectum and compress the urinary bladder, or childbirth might damage the pudendal nerves and later lead to anal weakness.
