Batch 4.

2. HUMERUS BONE:
• The humerus bone is the long bone in the
upper arm or forelimb that runs from the
shoulder to the elbow.
• It articulates proximally with the glenoid via
the glenohumeral (GH) joint and distally with
the radius and ulna at the elbow joint.

3. • The humerus bone consists of the head,
greater and lesser tubercles, anatomical
neck, surgical neck, shaft, and distal end.
• Head: Articulates with the scapula to form the shoulder
joint.
• Greater and Lesser Tubercles: Sites for muscle
attachment.
• Anatomical Neck: Marks the boundary between the head
and the tubercles.
• Surgical Neck: Common site for fractures.
• Shaft: Main portion of the bone.
• Distal End: Articulates with the radius and ulna at the
elbow joint.
Anatomy of Humerus

4. Connection Point:
• Joins the shoulder and the elbow, facilitating arm
movement.
Muscle Attachment:
• Provides attachment points for muscles involved
in shoulder and arm movements.
Function and Role:
• The humerus bone plays a crucial role in arm
movement and stability.
• It acts as a connection point for muscles and
ligaments that control shoulder and elbow
movements.

5. Fracture:
• Commonly occur at
the surgical neck, often
due to trauma or falls.
Osteoporosis:
• Weakens the bone,
increasing the risk of
fractures.
COMMON INJURIES AND
CONDITIONS:

6. THE ELBOW JOINT:
The elbow joint is a hinge joint formed
by the articulation of the humerus,
ulna, and radius bones.

7. • The elbow joint consists of three main bones:
the humerus, ulna, and radius.
• Ligaments, including the ulnar collateral
ligament and the radial collateral ligament,
provide stability to the joint.
ANATOMY OF ELBOW
JOINT:

8. Flexion:
This movement decreases the angle
between the bones of the arm at the
elbow joint, bringing the forearm
closer to the upper arm.
Extension:
This movement increases the angle
between the bones of the arm at the
elbow joint, straightening the arm.
Pronation:
This movement involves the rotation
of the forearm and hand so that the
palm faces downward or posteriorly.
Supination:
This movement involves the rotation
of the forearm and hand so that the
palm faces upward or anteriorly.
Function and Range of
Motion
• Movements that occur
in the sagittal plane.
• Rotational movements of
the forearm.

10. Golfer's Elbow (Medial
Epicondylitis):
• Inflammation of the tendons
on the inside of the elbow.
• Cause: Overuse during activities
like golf or repetitive flexion.
• Symptoms: Pain on the inner
elbow, weak grip.
• Treatment: Rest, ice, anti-
inflammatory meds, physical
therapy.
Tennis Elbow (Lateral
Epicondylitis):
• Inflammation of the
tendons on the outside of
the elbow.
• Cause: Overuse during
activities like tennis or
repetitive gripping.
• Symptoms: Pain on the outer
elbow, weak grip.
• Treatment: Rest, ice, anti-
inflammatory meds, physical
therapy.
.
Elbow Fractures:
• Can result from trauma
or overuse.
• Causes: Falls, sports
injuries, direct impact.
• Symptoms: Pain, swelling,
difficulty moving the elbow.
• Treatment:
Immobilization, pain
management, possible
surgery.
