Study Notes
Arm Muscles, Vessels, and Nerves
- The lab focuses anatomy of the arm, including muscles, blood vessels, and nerves.
- Learning objectives include identifying arm muscles and understanding their origin, insertion, and function.
- Also, identifying and understanding the principle arteries and veins, their branches, and tributaries.
- Learning to identify arm nerves and understand their origin, pathway, and distribution territories.
- Demonstrating arm movements, including flexion, extension, abduction, adduction, medial rotation, lateral rotation, and circumduction.
- Detailed anatomical diagrams illustrating the location and relationships of muscles, nerves, and vessels are included.
Muscle Anatomy Details
- Specific muscles mentioned include:
- Coracobrachialis
- Biceps brachii (short and long heads)
- Brachialis
- Triceps brachii (long, lateral, and medial heads)
- Deltoid
- Teres major and minor
- Brachioradialis
- Pronator teres
- Other muscles
- Origin, insertion, innervation, and action of these muscles are described.
Vascular Anatomy Details
- Principle arteries and veins of the arm, including the brachial artery and its branches (radial and ulnar arteries; profunda brachii artery, humeral nutrient artery, superior and inferior ulnar collateral arteries, and additional branches).
- Details on venous systems (superficial and deep veins); the basilic and cephalic veins are noted.
- The location of arteries and veins relative to other structures is discussed.
Nervous System Anatomy
