Synovial membranes are a type of connective tissue membrane that supports mobility in joints. 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. 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.

Ascending part - originates from the spinous processes of vertebrae T5-T12 (or T2-T12). It inserts into the medial end of the spine of the scapula. The ascending part supports and moves the scapula inferomedially. The skin is the body’s largest organ. It is part of the integumentary system, which includes skin, hair, nails, and fat.

The clitoral hood is the fold of skin that surrounds the head of the clitoris. It protects the clitoris from friction.

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. Transverse part - extends from the spinous processes of vertebrae T1-T4 (or C7-T3) to the acromion and superior crest of the spine of the scapula. This part supports and draws the scapula medially. A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body ( e.g., skin), lines an internal body cavity ( e.g., peritoneal cavity), lines a vessel (e.g., blood vessel), or lines a movable joint cavity (e.g., synovial joint). Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue membranes and epithelial membranes ( Figure 4.1.3). Figure 4.1.3 – Tissue Membranes: The two broad categories of tissue membranes in the body are (1) connective tissue membranes, which include synovial membranes, and (2) epithelial membranes, which include mucous membranes, serous membranes, and the cutaneous membrane, in other words, the skin. As you’ve seen above, the thorax contains more than thoracic arteries, nerves, and lymphatics. It also contains vital organs and structures, such as the heart, lungs, thymus, trachea, and esophagus.

Labia minora. These are the inner lips. They sit inside the outer lips but can be varying sizes. In some females, for example, the inner lips extend beyond the outer lips. Their main roles are to support and move the scapula superomedially. They also rotate the glenoid cavity inferiorly. The rhomboids are innervated by the dorsal scapular nerve (C5).All cells and tissues in the body derive from three germ layers: the ectoderm, mesoderm, and endoderm. The human structure can be described as bipedal, with hair covering the body, presence of mammary glands and a set of extremely well-developed sense organs. With respect to human body anatomy, we have a specialized circulatory system that enables the efficient transport of materials and nutrients within the body. Hercules: The influence of works by Lysippos". Paris: The Louvre . Retrieved 4 October 2020. In the fourth century BCE, Lysippos drew up a canon of proportions for a more elongated figure that that defined by Polykleitos in the previous century. According to Lysippos, the height of the head should be one-eighth the height of the body, and not one-seventh, as Polykleitos recommended.

Meanwhile, nerves in the skin relay information about external temperature. This may cause the brain to initiate involuntary responses that control body temperature, such as sweating or shivering. Partially digested food first travels through the small intestine, which comprises three parts: the duodenum, the jejunum, and the ileum. Most digestion and absorption of food happens here. These can include biochemical and physical interactions between various factors and components in our body. With the progress of evolution, organisms began to exhibit advanced characteristics and features that enabled them to be more efficient and thrive in their respective environment. 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 pelvis is one of two bones used to determine the sex of a skeleton, which is determined by examining the size of the greater sciatic notch (also known as the pelvic opening). The parietal lobe: Situated in the middle of the brain, the parietal lobe supports the identification of objects and spatial reasoning. It also plays a role in interpreting pain and touch signals.

The zygote divides into many cells. As these cells become specialized, they lose their ability to differentiate into all tissues. At first they form the three primary germ layers. Following the cells of the ectodermal germ layer, they too become more restricted in what they can form. Ultimately, some of these ectodermal cells become further restricted and differentiate in to nerve cells. The brain and spinal cord form the central nervous system, which works to process and send nerve signals, interpret information, and produce conscious thought.In insects, crustaceans, and the extinct trilobites, the thorax is one of the three main divisions of the creature's body, each of which is in turn composed of multiple segments. It is the area where the wings and legs attach in insects, or an area of multiple articulating plates in trilobites. In most insects, the thorax itself is composed of three segments; the prothorax, the mesothorax, and the metathorax. In extant insects, the prothorax never has wings, though legs are always present in adults; wings (when present) are restricted to at least the mesothorax, and typically also the metathorax, though the wings may be reduced or modified on either or both segments. In the Apocritan Hymenoptera, the first abdominal segment is fused to the metathorax, where it forms a structure known as the propodeum. Accordingly, in these insects, the functional thorax is composed of four segments, and is therefore typically called the mesosoma to distinguish it from the "thorax" of other insects.
