It consists of three sections: the upper arm, forearm, and hand. It extends from the shoulder joint to the fingers and contains 30 bones. It also consists of many nerves, blood vessels (arteries and veins), and muscles. The nerves of the arm are supplied by one of the two major nerve plexus of the human body, the brachial plexus. Aquatic and semiaquatic tetrapods usually have limb features (such as webbings) adapted to better provide propulsion in water, while marine mammals and sea turtles have convergently evolved flattened, paddle-like limbs known as flippers. In human anatomy, the upper and lower limbs are commonly known as the arms and legs respectively, although

Lower limb anatomy Author: Adrian Rad, BSc (Hons) • Reviewer: Nicola McLaren, MSc Last reviewed: September 11, 2023 Reading time: 21 minutes Recommended video: Regions of the lower limb [20:39] Like any structure in the human body, the knee also requires a neurovasculature supply. 12 Bones of the Lower Limb Bones of the Lower Limb. For reference, the figure below shows how all the bones of the lower limb fit together. Anterior view of the arrangement of bones in the pelvis and leg. Figure 6.1 in Human Anatomy, Color Atlas and Textbook by J.A. Gosling et al., 6 th edition (2017). Our upper limbs are free, mobile, and adapted for prehension. Each articulates with the trunk at the sternoclavicular joint. Our lower limbs have to bear the weight of the body when walking, runnning, jumping, or standing. They are united behind to the vertebral column at the sacroiliac joints and in front to each other at the symphysis pubis.

3D interactive models and tutorials on the anatomy of the lower limb, including the muscular compartments, osseus structures, blood supply and innervation.

Regional anatomy organizes the body into several body parts or regions: upper limbs, lower limbs, trunk (thorax, abdomen, pelvis, back), head, and neck. This approach divides teaching and learning into discrete regional didactic areas, each one containing its respective bones, joints , muscles, arteries, veins, nerves, lymphatics, and organs. For anatomists, the lower limb consists of the thigh (the upper leg), the leg (the lower leg), and the foot. The thigh consists of a single bone, the femur. The leg consists of two long bones, the tibia and fibula, and the sesamoid bone, the patella, that serves as the knee cap.
