Functions of the Arm
Functions of the Arm include:
- The arm provides the strength and dexterity needed to lift and carry objects of varying sizes and weights.
- It allows for precise movements for grasping objects, whether close or far away.
- The arm muscles allow pushing objects away from the body and pulling them closer, helping in activities such as opening doors and moving furniture.
- The hand and fingers, controlled by the arm muscles, enable the manipulation of objects for tasks like typing, writing, and handling tools.
- Arms play an important role in non-verbal communication through gestures, expressing emotions, emphasizing speech, and conveying information.
- In activities requiring balance or stabilization, such as during sports or physical exertion, the arm muscles contribute to maintaining equilibrium.
- The arms assist in supporting and stabilizing body weight during activities such as climbing, lifting oneself from a seated position, or performing exercises like push-ups.
Bones and Muscles in the Arm
The arm body part is the upper limb of vertebrates. Anatomy of the arm involves the detailed study of its bones, muscles, nerves, blood vessels, and connective tissues. Learning about the arm muscles and arm bones helps in understanding how movements are coordinated and how injuries can be prevented or treated.
In this article, we will cover the anatomy of the arm and read about the nerve supply and blood supply in the arm along with arm muscles and bones, in detail.
