Study Notes
Bony Landmarks
- The jugular notch is located between the sternum and the medial end of the clavicle.
- The greater tubercle is located on the humerus.
- The acromial end is the bony landmark found at the lateral (distal) end of the clavicle.
- The suprasternal notch is located at the superior border of the manubrium.
Muscles and Their Functions
- The deltoid muscle is responsible for shoulder abduction.
- The rhomboid muscle assists in scapular retraction.
- The teres major muscle is responsible for shoulder internal rotation.
- The trapezius muscle assists in scapular upward rotation.
Joints
- The sternoclavicular joint is located between the sternum and the medial end of the clavicle.
Aquatic Therapy
- Water support benefits athletes by reducing impact on joints during exercise.
- The buoyancy of water benefits athletes with joint injury or arthritis by reducing impact and stress on joints.
- The primary purpose of water-based exercise for athletes in aquatic therapy is to reduce impact on joints while maintaining cardiovascular fitness.
- The primary objective of aquatic therapy is to improve balance and coordination in athletes.
