Human Arm Bone Model With Blood Vessels

Osteological Precision: Features a 1:1 scale representation of the humerus, radius, and ulna, cast from specialized high-density resins that replicate the cortical bone density and tactile weight of a biological adult specimen.

Vascular Mapping: Incorporates a semi-flexible arterial network detailing the brachial, radial, and ulnar pathways, color-coded for clinical distinction and strategically positioned to demonstrate neurovascular relationship constraints during surgical simulation.

Quick Answer: The Human Arm Bone Model With Blood Vessels is an arm bone model with blood vessels: a skeleton of the upper limb with the main arteries, and usually the principal veins, laid along the bones. It shows how blood reaches the arm and hand and where pulses and veins are found.

Following the Arteries Down the Arm

The main artery of the upper limb changes name as it travels. It begins as the subclavian artery, becomes the axillary artery in the armpit and the brachial artery along the inner side of the humerus, then divides just below the elbow into the radial artery on the thumb side and the ulnar artery on the little-finger side. In the palm these two join again in the superficial and deep palmar arches, which send branches into each finger. Laying the vessels on bone shows why a fracture of the humeral shaft or elbow can threaten the circulation.

The superficial veins follow a different pattern. The cephalic vein runs up the thumb side of the forearm and arm, the basilic vein up the little-finger side, and the median cubital vein joins them across the front of the elbow, the site most often used for taking blood. Deeper veins run beside the arteries. Whether this model shows veins as well as arteries, and whether the shoulder girdle is included, is not stated in the title, so confirm the form.

Nursing and medical students use the model to find pulse points: the brachial pulse in the elbow crease, where a blood-pressure cuff is centred, and the radial pulse at the wrist. The human leg bone model with blood vessels teaches the lower limb in the same way, and the elbow joint model enlarges the region where the brachial artery divides.

Applications

Teaching the arterial supply of the upper limb in anatomy and physiology
Locating radial and brachial pulses before clinical observation practice
Explaining why the median cubital vein is used for venepuncture
Discussing vascular injury with humerus and elbow fractures

Care & Handling

Hold the arm model by the humerus and support the hand; the fine vessels around the fingers are the most fragile part.
Do not pull on the coloured vessels to point them out; use a probe or pencil tip instead.
Dust with a soft brush, then wipe the bones with a damp cloth, keeping moisture off any glued vessel joins.

Frequently Asked Questions

Where does the brachial artery divide?

Usually in the cubital fossa, just below the elbow crease, into the radial and ulnar arteries. The level varies between people, and a high division in the upper arm is a well-known anatomical variant.

Why is blood usually taken from the elbow crease?

The median cubital vein there is large, close to the surface and fairly fixed in place, and it lies over a protective sheet of tissue that separates it from the brachial artery and median nerve.

Where is the radial pulse felt?

At the front of the wrist on the thumb side, where the radial artery lies on the lower end of the radius and can be pressed against the bone with two fingers.

What are the palmar arches?

Two loops of artery in the palm formed by branches of the radial and ulnar arteries. They supply the fingers and allow blood to reach the hand even if one of the two arteries is blocked.

Why can a humerus fracture damage blood vessels?

The brachial artery runs close to the bone along the arm and at the elbow, so a sharp fragment or swelling can compress or tear it. Circulation in the hand is checked after such injuries.

How does the arm model compare with the leg model with blood vessels?

Both lay major vessels on bone, but the leg model follows the femoral, popliteal and tibial arteries and the saphenous veins. Using them together shows how the upper and lower limbs follow similar branching patterns.
