    Centrally located in the thorax, the sternum or breastbone is a long, flat bone that connects to the ribs via cartilage. It aids in protecting vital organs, notably the heart and lungs, from external harm.


    Part of the lymphatic system, the spleen is an organ located beneath the ribcage on the left side. It acts as a blood filter, removing old or damaged red blood cells. The spleen also plays a role in immune response by producing white blood cells.


    Situated at the base of the spine, the sacrum is a large, triangular bone formed by the fusion of several vertebrae. It connects the spine to the pelvis, providing stability and support to the upper body.


    These are cavities or spaces within the bones of the skull, lined with mucous membranes. Sinuses help in reducing the weight of the skull, humidifying and warming inhaled air, and enhancing voice resonance. The human skull has several sinuses, including the maxillary, frontal, ethmoidal, and sphenoidal sinuses.


    The body’s largest organ, the skin serves as a protective barrier against external threats, such as pathogens and harmful UV rays. It’s involved in temperature regulation, sensation, and vitamin D synthesis. The skin has multiple layers, including the epidermis, dermis, and subcutaneous tissue.

    Small Intestine

    Following the stomach in the digestive tract, the small intestine is a long, coiled organ responsible for the absorption of nutrients and minerals from food. It consists of three sections: the duodenum, jejunum, and ileum.

    Spinal Cord

    Housed within the vertebral column, the spinal cord is a cylindrical bundle of nerve fibers that transmits signals between the brain and the rest of the body. It plays a pivotal role in both motor and sensory functions.

    Situated in the middle ear, the stapes is the smallest bone in the human body. Along with the malleus and incus, it aids in transmitting sound vibrations from the eardrum to the inner ear.


    The longest muscle in the human body, the sartorius runs diagonally from the hip to the inside of the knee. It aids in flexing the hip and knee and is involved in rotating the thigh outward.

    Sebaceous Glands

    Embedded in the skin, primarily in the face and scalp, sebaceous glands produce sebum – an oily substance that moisturizes the skin and hair. It also provides a layer of protection against external contaminants.


    A fundamental component of the nervous system, synapses are junctions that allow nerve cells (neurons) to communicate with one another, transmitting signals via chemical or electrical means.
