Cholesterol molecules are found within the phospholipid bilayer to provide stabilization to the membrane. The phospholipid bilayer itself is a flexible, semi-permeable membrane that forms the barrier between cellular compartments. Glycolipids are fats with chains of identifying sugars on them, that allow the cell to be recognizable to other cells. Channel proteins allow the passage of certain substances, depending on their size and electrical charge and receptor tyrosine kinases are a specific class of cell membrane receptors.

The metaphysis is the area between the epiphysis and the diaphysis. It also contains the epiphyseal line/plate. The epiphysis is the end of a long bone. The marrow cavity is also known as the medullary cavity and it is where blood cells are produced. The cortical bone (also known as compact bone) is the dense outer layer of bone. 

Long bones are longer than they are wide, example being the femur (thigh bone), sesamoid bones are formed inside tendons, example being the patella (kneecap), flat bones are thin plates of bone, such as skull bones, irregular bones are those that do not fall in any other categories such as the sphenoid bone in the skull, short bones tend to be equal length and width such as metacarpals (wrist bones).

The diaphragm has 3 main hiatuses – The first is at T8 through which the IVC passes through.The second is at T10 through which the esophagus and vagus nerve pass and the final hiatus is at T12 through which the Aorta, azygous vein and the thoraci lymphatic duct. A helpful mneumonic for this is I ATE (8), TEN EGGS At 12. I is for IVC with the ATE representing T8. The TEN for T10 and the EGGS stand for Esophagus, two g's for the two vaGus and the At for Aorta, which passes through the diaphragm at T12.

The correct answer is the thoracic lympahtic duct. It drains the entire body excluding the right upper extremity and face. The venous system is separate from the lymphatic system, thus the superior vena cava, inferior vena cava and hepatic vein are incorrect answers. The thoracic lymphatic duct enters the venous circulation at the left subclavian vein.

The correct answer is the right lympahtic duct. It drains the right side of the body except for the right lower extremity which is drained by the thoracic duct. The venous system is separate from the lymphatic system, thus the superior vena cava, inferior vena cava and hepatic vein are incorrect answers. The thoracic lymphatic duct enters the venous circulation at the right subclavian vein.

The epidermis is composed of multiple layers of cells that are (from the outside to the inside): stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. The stratum basale is separated from the dermis by a basement membrane.

The apex of the heart in the adult is located near the left midclavicular line in the fifth intercostal space where the the apical heart pulse can be measured. Vertical surface lines are used to pinpoint major anatomical sites on the thorax.The midclavicular line is a line that runs vertically from a point that is midway on the clavicle, between the jugular notch and the acromion process of the scapula. The midaxillary line is a line that runs vertical from the axilla (armpit). The parasternal line is located midway between the sternal and midclavicular lines. The sternal line is a vertical line parallel to the margin of the sternum on either side.
