This flattened part of the skull and the depressed region above the zygomatic arch constitute the temporal fossa which in life is occupied by the temporalis muscle. 1 6. ANS -B: The middle meningeal artery and accessory meningeal artery are branches of the max illary artery that enter the cranial cavity through foramen spinosum and foramen ovale. 1 7. ANS -B: The buccal branch of the facial nerve is the motor fo r the buccinator muscle.

i) POSTERIOR: there is a prominent ridge (spine) that runs diagonally across the surface of the scapula. ANTERIOR: this surface is slightly hollowed out area. ii) The oval socket that has a shallow depression is the Glenoid cavity. B. Which bone is Stefan referring to as “collarbone”?
A prominent ridge called the spine runs diagonally across the posterior surface of the scapula. Hassan could have identified which were right and left, possibly by the medial border because the thick edge (lateral border) is closer to the arm. The glenoid cavity is the shallow depression that articulates with the head of the humerus. B. Which bone is Stefan referring to as the collarbone?
It also restructures the bone extracellular matrix, where the shape of a bone is changed slightly, so that the bone can support more stress, be stronger, and/or thicker. 7. Which marking of the skull articulates with the first cervical vertebra? The occipital condyles is the oval process with convex surface on either side of the foramen magnum and it articulates with the first cervical vertebra (atlas) which allows a person to nod their head “yes”. 8.
The shallow oval pocket of the scapula is the Glenoid cavity where the head of the humerous sits. B) Which bone is Stefan referring to as the “collarbone”? The bone that Stefan is referring to is the clavicle. C) Which surface markings could Stefan use to distinguish the right and left humerous? A surface marking that can distinguish left from right, is the medial epicondyle.
(1 point) The medial Collateral Ligament also known as the MCL is a band that runs in between the inner surfaces of the femur and the tibia. It endures forces acting starting on the outer surface of the knee which is called valgus forces, this stops the knee from collapsing inwards. The MCL has two parts; an inner part that
7- Which marking of the skull articulates with the first cervical vertebra? The occipital condyles articulate with the firt cervical vertebra. 8- Which bone forms the inferior part of the nasal septum? The bone that forms the inferior part of the nasal septum is the vomer. 9- How many bones make up the upper limb?
Finally, the cords give rise to various branches that supply the upper limb structures. I want to point out that although most of the branches to the upper limb muscles arise from the plexus in the axilla, some arise from the cervical (neck) part of the plexus. These nerves are the dorsal scapular, nerve to subclavius, long thoracic, and suprascapular. Needless to say, the brachial plexus is a very
The resonating system is located in the pharynx, oral cavity, and nasal cavities. The vocal tract is comprised of resonators which give a personal quality to the voice, and the modifiers or articulators which form sound into voiced sounds. There are three different cartilages used in our larynx which are the thyroid, cricoid, and arytenoid. The thyroid cartilage forms the front portion of the larynx; the most forward part comprises the "Adam's apple". The vocal folds attach just below the Adam's apple, and the thyroid cartilage also houses the vocal folds.
