Hundeherz mit Dissektion

This specimen preserves a superficial dissection of the lower hindlimb musculature from the mid-thigh to the foot, as well as nerves and vessels of the femoral canal and popliteal fossa.The insertions of the muscles of the thigh in the stifle joint and tibial bone are visible. The capsule of the stifle joint has been opened to demonstrate the menisci and the collateralligaments. Extensor and flexor muscles of the tarsus and fingers are exposed. The dissection preserves the topography of the lateral saphenous vein on the foot surface and caudal aspect of the leg Dorsal and palmar anatomical structures of the foot are dissected. Detailed anatomical description on request.

Dieses Präparat zeigt die Topographie des Herzens nach Entfernung des linken Lungenflügels bei der Dissektion der Brusthöhle und des kranialen Abdomens eines Hundes, der von der linken Seite betrachtet wird. Der kraniale und der akzessorische Lappen des rechten Lungenflügels bleiben in situ und dienen als anatomische Referenzpunkte. Im kranialen Mediastinum sind der Truncus brachiocephalicus und die linke Arteria subclavia als Hauptäste des Aortenbogens identifizierbar.Der thorakale Teil der Speiseröhre verläuft durch das Mediastinum in kraniokaudaler Richtung. Das Zwerchfell ist erhalten geblieben und dient als Orientierungshilfe für retrodiaphragmatische Organe wie Leber und Magen.Die Crura diaphragmatica und ihre Beziehung zum Hiatus aorticus bleiben erhalten, ebenso wie die ersten viszeralen Äste der abdominalen Aorta, insbesondere der Truncus celiacus und die kraniale Mesenterialarterie. Ein Teil der rechten Vorhofwand wurde entfernt, um die rechte atrioventrikuläre (trikuspidale) Klappe einschließlich der Chordaetendineae und Papillarmuskeln freizulegen.Darüber hinaus ist das Septomarginaltrabekel (Moderatorenband) innerhalb der rechten Herzkammer sichtbar, ebenso wie der Weg von der Herzkammer zum Truncus pulmonalis.Die linke Vorhofwand ist ebenfalls geöffnet, um ihr Lumen zu zeigen.

This specimen demonstrates the superficial anatomy of a dog's right thoracic limb from the scapula to the hand. The shoulder flexor and extensor muscles of the scapular region have been preserved, along with the arm flexor and extensor muscles of the elbow. In the forearm and hand are the flexor and extensor muscles of the carpus and fingers. On the medial side of the axillary region the main nerves of the brachial plexus have been preserved. Similarly, the paths of the brachial and median arteries and their respective veins are identified. In a superficial position, the cephalic vein has been preserved together with the antebrachialis lateral cutaneous nerve of the forearm. Detailed anatomical description on request.

Superficial anatomical structures:Tip of the nose (Apez nasi)Right and left wings of the nose (Alae nasi)Nonglandular skin on the tip of the nose (Planun nasale)Superficial disscetion on the left side:On the left side, the skin has been removed to identify the main anatomical structures,which are described grouped below.Muscles of the facial neuromuscular system:• M. nasolabial levator (M. levator nasolabialis)• M. canine (M. caninus)• M. buccinator (M. buccinator)• M. Zygoma9c (M. zygoma:cus)• M. parodidoauricularisMuscles of the mandibular neuromuscular system (mas9cators):• M. masseter (M. masseter)• M. Temporary (M.temporalis)Nerves:• Facial nerve: (N . facialis)• Dorsal buccal Branch (Rami buccales)• Ventral buccal Branch (Rami buccales)• Bucolabial branches (Rami buccolabiales)• N. Auriculopalpebral (N. Auriculopalpebralis)Vascular:• Facial artery (Arteria facialis)• External jugular vein: (V. Jugularis externa)o Maxillary vein (V. Maxillaris)o Linguofacial vein (V. Linguofacialis)Salivary glands:• Parotid gland and paro9d duct (Glandula parotis) (Ductus parotideus)• Mandibular gland Glandula mandibularisLymph nodes:• N. L. mandibular (Lymphonodi mandubulares)Deep dissection on the right side:On this right side mandible has been removed to see deeper anatomical structures. You can see the surfaces of the temporal bone for the temporomandibular joint (Articulatio Temporomandibularis). The medial pterygoid muscle (M. pterygoideus medialis) is identified and sectioned in its insertion area to the ramus of the mandible (Ramus mandibulae). Next to this muscle, the branches of the mandibular nerve (N. mandibularis) are identified, as well as the maxillary nerve (nevus maxillaris) and the maxillary artery (arteria maxillaris). Near the external acoustic meatus (Meatus acusticus externus), the facial nerve (N . facialis) has been maintained, with one of its branches,the auriculopalpebral nerve (N. Auriculopalpebralis), running parallel to the zygomatic arch (Arcus zygomaticus), visible atier removing the parotd salivary gland (Glandula parotis). The tongue is identified in its entire caudal extension, and the styloglossus (M. stylogossus), genioglossus (M. genioglossus) and genihyoid (M. geniohydeus) muscles reach it. Next to these muscles, the hypoglossal nerve (N. hypoglossus) is identified. In relation to the pharynx (Pharynx), the constrictor muscles of the pharynx (Mm. constrictors phyngis caudalis) are identified. In the most caudal area, in relation to the neck, the course of the common caro9d artery (arteria caarotis communis) and the vagosympathetic trunk nerve (Truncus vagosympathicus) are identified.
