Briefly write about the human appendicular skeleton.

The human appendicular skeleton consists of the bones of the limbs and the girdles that attach them to the axial skeleton. It includes:

  1. Upper Limbs:

    • Arms: Comprising the humerus (upper arm bone), radius, and ulna (forearm bones).
    • Hands: Including the carpals (wrist bones), metacarpals (palm bones), and phalanges (finger bones).

  2. Lower Limbs:

    • Legs: Comprising the femur (thigh bone), tibia, and fibula (lower leg bones).
    • Feet: Including the tarsals (ankle bones), metatarsals (foot bones), and phalanges (toe bones).

  3. Girdles:

    • Pectoral (Shoulder) Girdle: Composed of the clavicles (collarbones) and scapulae (shoulder blades), connecting the upper limbs to the axial skeleton.
    • Pelvic Girdle: Made up of the hip bones (ilium, ischium, and pubis), attaching the lower limbs to the axial skeleton.

The appendicular skeleton supports movement and helps with tasks such as walking, running, lifting, and grasping.
