The endocrine system is a network of glands throughout the body. These glands release important chemicals called hormones, which help regulate the function of virtually every organ and organ system in the body. This is the result of humans having ancestors that began walking on their hind limbs rather than using all four limbs. Most of our anatomical insight was gained through the dissection of corpses (cadavers), and for a long time, it was the only way we could gain anatomical knowledge about the human body. It was a rather grotesque affair, but it made up the bulk of medical literature for centuries. These days, technological innovation has made it possible to explore human anatomy at a microscopic level. Also known as the womb, the uterus is a pear-shaped organ where the fetus grows. The cervix is the route to the vagina and gateway for sperm to enter. Vagina acts as the route for a penis to enter during intercourse and the exit of the fetus during delivery. The fallopian tubes connect the ovaries to the uterus. When the ovaries release an egg, the egg travels down the fallopian tube toward the uterus for potential fertilization.

Areola. The areola is the pigmented area that surrounds the nipple. It is circular and varies in size from person to person. It contains small glands, called Montgomery glands, that secrete lubrication to keep the nipple from drying out, especially when nursing. Hughes, S. M.; Gallup, G. G. Jr. (2003).

Male SHRs (M=1.18±0.071, range 1.03–1.40) significantly (t=10.41, P<.01) exceeded female SHRs (M=1.03±0.066, range 0.90–1.22). Here and subsequently, M signifies mean±standard deviation. (These are head-on lateral widths, not circumferences.) The circulatory system includes the many blood vessels that circulate blood throughout the body. It includes veins, arteries, capillaries, venules, and arterioles. The kidneys also produce urine when they remove waste from the blood. Urine flows out of the kidneys through the ureters, then down to the urinary bladder.Subluxation: Injury to the muscles and ligaments in the spine can cause the vertebrae to partially dislocate, which can also damage the spinal cord.

For example, progesterone helps regulate the menstrual cycle and plays an important role in sustaining a pregnancy. Longissimus cervicis - attaches to the transverse processes of T1-T5 and transverse processes of C2-C6. In a healthy person, the liver releases bile into the gallbladder, which the gallbladder stores and then releases to travel down the common bile duct into the small intestine to aid digestion. The main anatomical planes of the human body, including median (red), parasagittal (yellow), frontal or coronal plane (blue) and transverse or axial plane (green).

The membrane lines the joint cavity and contains fibroblasts that produce hyaluronan, which leads to the production of synovial fluid, a natural lubricant that enables the bones of a joint to move freely against one another.
