When anatomists refer to the right and left of the body, it is in reference to the right and left of the subject, not the right and left of the observer. When observing a body in the anatomical position, the left of the body is on the observer's right, and vice versa. These standardized terms avoid confusion. Examples of terms include: [2]: 4
Abrasions on elbow and lower arm. The elbow wound will produce a permanent scar. A first-degree abrasion involves only epidermal injury. A second-degree abrasion involves the epidermis as well as the dermis and may bleed slightly. A third-degree abrasion involves damage to the subcutaneous layer and the skin and is often called an avulsion.
For example, if a patient's entire back (18%) and entire left leg (18%) are burned, about 36% of the patient's BSA is affected. The BSAs assigned to each body part refer to the entire body part. [4] So, for example, if half of a patient's left leg were burned, it would be assigned a BSA value of 9% (half the total surface area of the leg).
Christ after his Resurrection, with the ostentatio vulnerum, showing his wounds, Austria, c. 1500. The five wounds comprised 1) the nail hole in his right hand, 2) the nail hole in his left hand, 3) the nail hole in his right foot, 4) the nail hole in his left foot, 5) the wound to his torso from the piercing of the spear.
The main artery in the arm is the brachial artery. This artery is a big continuation of the axillary artery. The point at which the axillary becomes the brachial is distal to the lower border of teres major. The brachial artery gives off an unimportant branch, the deep artery of arm. This branching occurs just below the lower border of teres major.
For example, the right arm and leg are controlled by the left, contralateral, side of the brain. Ipsilateral (from Latin ipse 'same'): on the same side as another structure. [25] For example, the left arm is ipsilateral to the left leg. Bilateral (from Latin bis 'twice'): on both sides of the body. [26]

A wound is any disruption of or damage to living tissue, such as skin, mucous membranes, or organs. [1] [2] Wounds can either be the sudden result of direct trauma (mechanical, thermal, chemical), or can develop slowly over time due to underlying disease processes such as diabetes mellitus, venous/arterial insufficiency, or immunologic disease.
