The urinary bladder and internal reproductive organs, including the uterus, ovaries, and testes, are in the pelvic cavity. The pelvic cavity is a bony structure formed by the pelvis and contains the terminal portions of the digestive tract, urinary tract, and reproductive tract. It is situated inferior to the abdominal cavity and is separated from it by the pelvic brim, which is a rim of bone formed by the iliac crests, sacrum, and pubic bones. The pelvic cavity is bounded by the pelvic bones and the pelvic diaphragm and is lined with pelvic peritoneum.

The quadriceps femoris group is a group of four muscles located in the anterior compartment of the thigh. These muscles are responsible for extending the leg at the knee joint. The four muscles that make up the quadriceps femoris group are the rectus femoris, vastus medialis, vastus intermedius, and vastus lateralis.

The vastus lateralis is the largest of the four muscles and is located on the lateral side of the thigh. It originates from the greater trochanter of the femur, the lateral lip of the linea aspera, and the lateral intermuscular septum. It inserts into the patella and the tibial tuberosity via the patellar tendon. The vastus lateralis is responsible for extending the leg at the knee joint and is also involved in stabilizing the patella.

Blood then carry them to target cells or organs throughout the body. Hormones are chemical messengers that help to regulate various physiological processes such as growth, metabolism, and reproduction. Unlike exocrine glands (option a), which secrete their products into ducts that carry them to external surfaces such as the skin or digestive tract, endocrine glands have no ducts and release their secretions directly into the circulatory system. Salivary glands (option d) are exocrine glands that secrete saliva into ducts leading to the mouth. Option b is also incorrect as it does not accurately describe endocrine glands.

A hinge joint is a type of synovial joint that allows movement in only one plane, like a door hinge. The elbow joint is made up of the humerus bone in the upper arm, the ulna bone and the radius bone in the forearm. It allows flexion and extension movements, like the opening and closing of a hinge.
