Which of the following is NOT part of the axial division of the body

A. Hip: The coxal joint, also known as the hip joint, is the articulation between the head of the femur and the acetabulum of the pelvic bone. It is a ball-and-socket joint that provides stability and mobility.

B. Foot: The foot contains joints such as the tarsal, metatarsal, and phalangeal joints, which allow for movement and weight bearing. However, none of these are referred to as the coxal joint.

C. Hand: The hand has numerous joints including carpals, metacarpals, and phalanges. These joints support fine motor skills but are not associated with the coxal joint.

D. Groin: The groin is the area where the thigh meets the lower abdomen. Although anatomically close to the hip region, the coxal joint itself is specifically part of the hip rather than the groin.

A. A long fatty acid chains: Triglycerides with long fatty acid chains can be either saturated or unsaturated. The chain length affects melting point to some extent but does not solely determine whether the fat is a solid or liquid at room temperature.

B. Saturated fatty acids: Saturated triglycerides have no double bonds, making their fatty acid chains tightly packed. This structure leads to higher melting points, so they are generally solid at room temperature, as seen in butter or lard.

C. Unsaturated fatty acids: Unsaturated triglycerides contain one or more double bonds in their fatty acid chains, which introduce kinks that prevent tight packing. This structure lowers their melting point, making them liquid at room temperature and therefore classified as oils.

D. A high water content: Triglycerides are hydrophobic molecules that do not mix with water. Their classification as oils or fats depends on the degree of saturation of fatty acids, not water content, since triglycerides themselves contain virtually no water.
