Study Notes

Anatomical Structures

Muscles: Numerous muscles are labeled and categorized by their origins, insertions, and attachments. Examples include the trapezius, deltoid, pectoralis major, latissimus dorsi, biceps brachii, triceps brachii, and many more.
Ligaments: Various ligaments are detailed, including costoclavicular, coracoclavicular, trapezoid, and conoid ligaments, among others.
Bones: The humerus, radius, ulna, clavicle, and scapula are identified, with specific anatomical features like epicondyles, tubercles, and facets noted.
Nerves: The brachial artery, radial nerve, ulnar nerve, median nerve, and their branches are identified and illustrated.
Arteries: Several arteries are labeled, including the brachial artery, axillary artery, profunda brachii artery, radial artery, ulnar artery, and their branches.

Elbow Joint Structures

Ligaments: The radial collateral ligament and ulnar collateral ligament stabilize the elbow.
Capsule: A joint capsule encloses the elbow joint.
Bones: The humerus, radius, and ulna are the bones forming the elbow joint.
Tubercles: The radial and ulnar tuberosities are visible attachment points for muscles.

Anatomical Diagrams

Anterior and Posterior Views: Diagrams present the same area from both sides of the body, emphasizing anatomical placement and relationships.
Muscle Attachments: Illustrations clearly demonstrate the origins and insertions of muscles.
Nerve and Artery Pathways: The pathways of nerves and arteries are shown in several diagrams.
Detailed Labeling: Labels explicitly identify every anatomical structure present in the visual.

Clinical Conditions

Claw Hand Deformity: This condition affects the hand's shape, usually caused by issues related to nerve function.
