About this deal

Portion of the thymus, adipose and connective tissue, lymph nodes, branches of internal thoracic vessels, sternopericardial ligaments The vagina can vary in size, but the average length is about 2.5 to 3 inches. That said, it expands in length during arousal. The major pathophysiologies encountered in blunt chest trauma involve derangements in the flow of air, blood, or both in combination. Sepsis due to leakage of alimentary tract contents, as in esophageal perforations, also must be considered. Blunt trauma commonly results in chest wall injuries (e.g., rib fractures). The pain associated with these injuries can make breathing difficult, and this may compromise ventilation. Direct lung injuries, such as pulmonary contusions (see the image below), are frequently associated with major chest trauma and may impair ventilation by a similar mechanism.

The earliest known representations of female figures date from 23,000 to 25,000 years ago. [17] Models of the human head (such as the Venus of Brassempouy) are rare in Paleolithic art: most are like the Venus of Willendorf– bodies with vestigial head and limbs, noted for their very high waist:hip ratio of 1:1 or more. [17] It may be that the artists' "depictions of corpulent, middle-aged females were not 'Venuses' in any conventional sense. They may, instead, have symbolized the hope for survival and longevity, within well-nourished and reproductively successful communities." [17]The muscles of the stomach help it break down and digest food. Within its lumen lining, certain regions of the stomach also produce enzymes that help digest food. The enzyme pepsin, for example, breaks down proteins so that they can become amino acids. The brain and spinal cord form the central nervous system, which works to process and send nerve signals, interpret information, and produce conscious thought.

Pyramidalis is a small triangular muscle found in the lower abdomen. It lies anterior to the rectus abdominis muscle. It extends from the pubic symphysis and pubic crest to the linea alba. The action of this muscle is to tense the linea alba, which is initiated by the subcostal nerve. Pyramidalis is a variable muscle of the abdominal wall, being absent in about 20% of the population. A heroic figure, used in the depiction of gods and superheroes, is eight-and-a-half heads tall. Most of the additional length comes from a bigger chest and longer legs. Bogin, B; Varela-Silva, M. I. (2010). "Leg length, body proportion, and health: A review with a note on beauty". International Journal of Environmental Research and Public Health. 7 (3): 1047–75. doi: 10.3390/ijerph7031047. PMC 2872302. PMID 20617018. The thoracic spine: The thoracic spine is the middle part of the spine, connecting the cervical and lumbar spine. It has 12 vertebrae. The thoracic spine helps keep the body upright and stable.The reproductive system works closely with other organs and organ systems. For example, the hypothalamus and pituitary gland help regulate the production and release of hormones such as estrogen and testosterone. Superficial layer containing the trapezius, latissimus dorsi, rhomboid major and minor and levator scapulae muscles. The next set of torso muscles are found in the intercostal spaces between the ribs. The intercostal muscles consist of a group of three layered muscles, from superficial to deep: external, internal and innermost intercostals. The core is used to stabilize the thorax and the pelvis during dynamic movement and it also provides internal pressure to expel substances (vomit, feces, carbon-laden air, etc.). The core is traditionally assumed to originate most full-body functional movement, including most sports. In addition, the core determines to a large part a person's posture. In all, the human anatomy is built to take force upon the bones and direct autonomic force, through various joints, in the desired direction. The core muscles align the spine, ribs, and pelvis of a person to resist a specific force, whether static or dynamic. [3] Static core function [ edit ]

The portion of nervous system that communicates with the central nervous system is called the peripheral nervous system. Overall, the peripheral and central nervous systems also include an extensive network of neurons. Located throughout the body, these fibrous bundles send information about sensation, temperature, and pain. Kidneys are paired bean-shaped organs placed retroperitoneally. The kidneys have a rich blood supply provided by the renal artery. Nephrons within the kidneys filter the blood that passes through their web of capillaries ( glomerulus). The blood filtrate then passes through a series of tubules and collecting ducts, eventually forming the The coccyx: The coccyx is the base, or tailbone, of the spine. This consists of four vertebrae fused together. It joins to ligaments and muscles around the pelvis.All cells and tissues in the body derive from three germ layers: the ectoderm, mesoderm, and endoderm. The organs, muscles, and other contents of the torso are supplied by nerves, which mainly originate as nerve roots from the thoracic and lumbar parts of the spinal cord. Some organs also receive a nerve supply from the vagus nerve. The sensation to the skin is provided by the lateral and dorsal cutaneous branches.
