b. The C-shaped cartilages are stacked one on top of the other and start under the cricoids cartilage, and then continue to the throat to the stomach (AnatomyExpert, 2014). 14. Temporalis muscle a. The temporalis muscle originates on the temporal fossa, and inserts onto the cornoid process of the mandible (Starkey, et al., 2011). b. Its main function is to aid in biting (Starkey, et al., 2011). 15. Masseter muscle a. The masseter muscle originates on the zygomatic arch, and inserts onto the…

is complete with minor air sinuses. The mastoid notch is a groove that is medial to the mastoid process and is the basis of the digastric muscle, which opens the mouth. The petrous part is on the cranial floor and separates the cranial fossa from the posterior fossa. On its posteromedial surface there is an opening called the internal acoustic meatus that allows route of the vestibulocochlear nerve, transporting signals from the inner ear to the brain for balance and hearing. The inferior…

Fossa fossana, otherwise known as the Malagasy Civet or even Striped Civet is an euplerid only found in Madagascar. The Malagasy Civet is a small (About 26.9 inches head to tail), nocturnal mammal. Found throughout Madagascar in rain forests and lowlands, the Malagasy Civet creates a couple and claims territory. The niche of the Malagasy Civet is to feed upon invertebrates, small amphibians and some small mammals. The Fossa fossana typically sleeps in hollow trees and rock crevasses during the…

developmental malformations that arise from the unexplained splitting or tearing of the arachnoid membrane. • In some cases, arachnoid cysts occurring in the middle fossa are accompanied by underdevelopment (hypoplasia) or compression of the temporal lobe. The exact role that temporal lobe abnormalities play in the development of middle fossa arachnoid…

on the joint has resulted in bony calcification around the acetabular fossa (Wolff’s law), limiting the motion and increasing the likelihood of a more serious hip injury. Doctors have also noted a slight varus alignment at the knees joint as a potential contributing factor. The hip consists of a ball-n-socket joint in which the convex head of the femur sits in the concave acetabular fossa of the os coxa. The acetabular fossa includes a of fibrocartilage labrum which functions to deepen the…

A 36 year-old man presented with three weeks history of enlarging left neck swelling, which was mildly painful. There was no prior history of upper respiratory tract infection. Clinical examination revealed a 5 cm x 5 cm cystic mass at the level II of left neck anterior to sternocleidomastoid muscle. It was soft, mobile, and tender on palpation with normal overlying skin. Nasal endoscopy did not detect any abnormality then. The total white cells count was raised at 12,000/mm3. He was diagnosed…

Pain was more towards the right fossa. It was insidious in onset, moderate in intensity and pain was not relieved with anti-inflammatory drugs. The patient had no history of fever, no vaginal discharge. Past and family history was not of significance. No other significant history was noted…

11. Extensor pollicis brevis a. The extensor pollicis brevis originates on the posterior distal surface of the radius, and inserts on the proximal posteriolateral surface of the thumb (AnatomyExpert, 2014). b. Its main functions are to extend the metacarpal bone and the 1st phalanx (AnatomyExpert, 2014). 12. Abductor pollicis longus a. The abductor pollicis longus originates on the middle posterior surface of the ulna and radius, and inserts onto the proximal posteriolateral end of the 1st…
