3. Describe the anatomical relations of upper limb.
- The upper limb is composed of the arm, forearm, and hand.
- The bones of the upper limb are the scapula, humerus, radius, ulna, carpals, metacarpals, and phalanges.
- The muscles of the upper limb are divided into three groups: the shoulder muscles, the arm muscles, and the forearm muscles.
- The nerves of the upper limb are the brachial plexus, the radial nerve, the median nerve, and the ulnar nerve.
- The blood vessels of the upper limb are the axillary artery, the brachial artery, and the radial, ulnar, and median arteries.
- The lymph nodes of the upper limb are located in the axillary and subclavian regions.
4. Describe the development of upper limb.
- The upper limb develops from the lateral plate mesoderm.
- The limb bud forms and grows through the process of embryonic development.
- The limb bud differentiates into the arm, forearm, and hand.
- The bones, muscles, nerves, blood vessels, and lymph nodes of the upper limb develop through a series of complex processes.
5. Describe the anatomical pathways of upper limb.
- The brachial plexus arises from the spinal cord and supplies the muscles of the upper limb.
- The radial nerve supplies the muscles of the arm and forearm.
- The median nerve supplies the muscles of the forearm and hand.
- The ulnar nerve supplies the muscles of the hand.
- The axillary artery supplies the muscles of the upper limb.
- The brachial artery supplies the muscles of the arm and forearm.
6. Describe the muscle action sequence of upper limb.
- The muscles of the upper limb act in a sequence to perform movements such as flexion, extension, pronation, and supination.
- The muscles of the shoulder act to flex, extend, and rotate the arm.
- The muscles of the arm act to flex and extend the forearm.
- The muscles of the forearm act to flex and extend the wrist and fingers.
- The muscles of the hand act to flex and extend the fingers and thumb.
7. Describe the lymphatic drainage of upper limb.
- The lymph nodes of the upper limb drain into the axillary and subclavian lymph nodes.
- The lymphatic vessels of the upper limb drain into the thoracic duct.
- The thoracic duct drains into the bloodstream.
