The forearm is the region of the upper limb between the elbow and the wrist, consisting of two primary bones, the radius and ulna, which work in conjunction to allow for a wide range of motion. It is also home to numerous muscles, nerves, and blood vessels that facilitate movement and sensory functions of the hand and wrist.

The radius of a circle or sphere is the distance from its center to any point on its boundary, serving as a fundamental measure in geometry. It is crucial in calculating other properties such as the diameter, circumference, and area, and is used in various mathematical and physical applications.

Radius

The ulna is one of the two long bones in the forearm, located on the side opposite the thumb, and plays a crucial role in forming the elbow joint and stabilizing the forearm. It works in conjunction with the radius to allow for a wide range of motion in the arm, including pronation and supination.

Ulna

Muscles are specialized tissues in the body responsible for producing movement and maintaining posture through contraction and relaxation. They are classified into three types: skeletal, cardiac, and smooth, each with distinct structures and functions tailored to their roles in the body.

Muscles

Nerves

Blood vessels are integral components of the circulatory system that transport blood throughout the body, ensuring the delivery of oxygen and nutrients to tissues and the removal of waste products. They are classified into three main types: arteries, veins, and capillaries, each serving distinct functions in maintaining circulatory efficiency and homeostasis.

Blood Vessels

Movement is when something changes its place or position. It's like when you walk, run, or jump from one spot to another.

Movement

Sensory functions are the physiological processes that allow organisms to perceive and respond to stimuli in their environment through specialized sensory organs. These functions are crucial for survival, enabling organisms to detect changes in their surroundings and react appropriately to maintain homeostasis and avoid harm.
