Thorax model MP1521

for teaching

This high-resolution 3D printed specimen displays a detailed dissection of the right thoracic wall, axilla, and root of the neck, offering exceptional anatomical insight from the parasagittal section to the proximal arm. Thoracic Wall & Intercostal Region With the viscera removed, the model exposes ribs, intercostal muscles, and the neurovascular bundles deep to the parietal pleura. The serratus anterior shows clear digitations on the lateral chest wall. Pectoral Region & Axilla The pectoralis major is reflected to reveal pectoralis minor, which divides the axillary artery into three parts. The clavicle is partially removed, retaining the subclavius muscle. The cephalic vein runs in the deltopectoral groove, passing through the clavipectoral fascia. Brachial Plexus & Nerves The brachial plexus is preserved from C5–T1 roots to major terminal branches: - Musculocutaneous, Median, Ulnar, Radial, Axillary - Lateral and medial pectoral nerves - Long thoracic nerve (on serratus anterior) - Thoracodorsal nerve (with accompanying artery) - Dorsal scapular and suprascapular nerves - Axillary nerve with posterior circumflex humeral artery Also visible: the phrenic nerve crossing the scalenus anterior, plus a thin accessory phrenic nerve. Arteries & Veins Clearly shown arterial branches: - Thoracoacromial, Lateral thoracic, Thoracodorsal, Circumflex humeral arteries - Transverse cervical and suprascapular arteries (from the subclavian artery) Most deep veins are removed for visibility, except the cephalic vein. Posterior Neck & Shoulder Muscles Visible muscles include: - Latissimus dorsi, teres major, trapezius, rhomboid major
