KMU Medicine 111 – Gross Anatomy Laboratory Flashcards

These flashcards cover key concepts and anatomical details from the KMU Medicine 111 Gross Anatomy Laboratory course, focusing on head, neck, and pelvic anatomy.

What is the primary function of the masseter muscle?

The masseter muscle is responsible for the elevation of the mandible during chewing.

What are the branches of the maxillary artery in the infratemporal fossa?

The branches include the middle meningeal artery, anterior and posterior deep temporal arteries, buccal artery, masseteric artery, inferior alveolar artery, and various others.

What is the anatomical significance of the zygomatic arch?

The zygomatic arch is involved in the formation of the cheekbone and serves as an attachment point for facial muscles.

What structures are preserved during the removal of the ramus of the mandible?

Auriculotemporal nerve and inferior alveolar nerve and vessels are preserved.

Identify the nerves responsible for sensory innervation of the skin over the anterior and lateral head.

The trigeminal nerve (CN V) provides sensory innervation through its branches, specifically the maxillary and mandibular divisions.

What are the contents of the carpal tunnel?

The contents include the median nerve and the tendons of the flexor digitorum superficialis and profundus, and flexor pollicis longus.

Describe the relationship between the ulnar artery and the superficial palmar arch.

The ulnar artery divides into a superficial branch that contributes to the formation of the superficial palmar arch.

What is the role of the deep perineal pouch in male anatomy?

The deep perineal pouch contains structures such as the deep transverse perineal muscle, urethra, and other associated nerves and vessels.

What is the arterial supply to the penis?

The arterial supply primarily comes from the internal pudendal artery, which gives rise to the dorsal artery and the deep artery of the penis.

What is the function of the levator ani muscle in the pelvis?

The levator ani muscle supports pelvic organs and assists in urinary and fecal continence.
