Exploring the Humerus Bone

What is the primary function of the humerus bone?

• To store calcium and phosphorus for the body.

• To support the weight of the body while standing.

• The primary function of the humerus bone is to facilitate movement of the arm.

• To protect the heart and lungs.

Which two joints does the humerus connect?

• Knee joint, Ankle joint

• Hip joint, Wrist joint

• Wrist joint, Shoulder joint

• Shoulder joint, Elbow joint

What are the main parts of the humerus?

• Scapula, clavicle, radius

• Trochlea, coronoid process, olecranon

• Head, greater tubercle, lesser tubercle, shaft, medial epicondyle, lateral epicondyle

• Femur, tibia, fibula

What is the anatomical term for the upper end of the humerus?

• humeral shaft

• humeral neck

• humeral head

• humeral tuberosity

Which muscle groups are primarily associated with the humerus?

• Pectoralis major, deltoid, biceps brachii, triceps brachii, rotator cuff muscles

• Gluteus maximus

• Hamstrings

• Quadriceps

What is the significance of the greater and lesser tubercles?

• They are locations for fat storage.

• They are sites for nerve attachment.

• They are involved in blood circulation.

• The greater and lesser tubercles serve as muscle attachment points, crucial for shoulder stability and movement.

How does the humerus contribute to arm movement?

• The humerus is primarily responsible for blood circulation.

• The humerus serves as a protective casing for the heart.

• The humerus connects the shoulder to the spine.

• The humerus acts as a lever for muscles, facilitating arm movement.

What are common injuries associated with the humerus?

• Back injuries, neck sprains, and hip dislocations.

• Tendonitis, sprains, and wrist injuries.

• Knee injuries, ankle fractures, and shoulder strains.

• Fractures, dislocations, and elbow injuries.

What is the role of the humerus in the skeletal system?

• The humerus supports the arm and enables movement at the shoulder and elbow joints.

• The humerus is responsible for blood circulation in the body.

• The humerus protects the heart and lungs in the chest cavity.

• The humerus is a bone in the leg that supports walking.

How does the structure of the humerus differ between species?

• The humerus only varies in color between species.

• The humerus is identical across all species.

• The humerus has no relation to locomotion or environment.

• The humerus differs in length, robustness, and muscle attachment sites across species, reflecting adaptations to their specific locomotion and environmental needs.
