Located just behind the external acoustic meatus, and lateral to the styloid process this cranial structure provides a point of attachment for the digastric and sternocleidomastoid muscles. Located just behind the external acoustic meatus, and lateral to the styloid process this cranial structure provides a point of attachment for the digastric and sternocleidomastoid muscles. Which of the following is it?
Correct Answer
D. The Mastoid Process
Explanation
The mastoid process is located just behind the external acoustic meatus and lateral to the styloid process. It serves as a point of attachment for the digastric and sternocleidomastoid muscles. The other options listed are not located in the same area or do not serve as attachment points for these muscles.

8.
Which of the following are paired bones?
Correct Answer(s)
A. Maxilla
C. Temporal
Explanation
The maxilla and temporal bones are paired bones in the human body. The maxilla is the upper jawbone, forming the central part of the facial skeleton, while the temporal bones are located on each side of the skull, near the temples. They house the middle and inner ear structures and also provide attachment points for various muscles involved in chewing and jaw movement.
9.
Forms at L5 With the Caval opening into the Thoracic cavity at T8?
Correct Answer
A. Inferior Vena Cava
Explanation
The correct answer is Inferior Vena Cava. The explanation for this is that the Inferior Vena Cava is a large vein that carries deoxygenated blood from the lower body to the right atrium of the heart. It forms at the level of the fifth lumbar vertebra (L5) and enters the thoracic cavity at the level of the eighth thoracic vertebra (T8). This positioning allows it to receive blood from the lower extremities and abdominal organs and transport it back to the heart for oxygenation.
10.
Begins at 2nd right costal cartilage..ends at the upper border of the 2nd right sternoclavicular articulation.
Correct Answer
A. Brachiocephalic Artery/Trunk (Inominate Artery)
Explanation
The correct answer is the Brachiocephalic Artery/Trunk (Inominate Artery). This artery begins at the 2nd right costal cartilage and ends at the upper border of the 2nd right sternoclavicular articulation.
11.
Branches of (Descending Aorta) Thoracic Aorta?
Correct Answer(s)
A. • Bronchial Arteries (A Visceral Branch)
B. • Mediastinal Arteries (A Somatic Branch)
C. • Pericardial Arteries (A Visceral Branch)
D. • Superior Phrenic Artery (A Somatic Branch)
E. * The Posterior Intercostal Arteries (Somatic Branches)
Explanation
** The Posterior Intercostal Arteries make connection (Anastamose) with the Anterior Intercostal Arteries which are ‘Fed” by the Internal Thoracic Arteries coming off both left and Right Subclavian Arteries.
(Visceral: refers to Organ structures)
(Parietal: refers to the walls of or a part of a structure)
(Somatic: relating to the wall of a structure)
12.
Begins at the level of the 2nd costal cartilage...ends at the superior border of the thyroid cartilage?
Correct Answer
A. Left Common Carotid Artery
Explanation
The left common carotid artery is the correct answer because it is the only option that begins at the level of the 2nd costal cartilage and ends at the superior border of the thyroid cartilage. The other options do not match this description.
13.
Begins at a point at the lateral border of the first rib and extends to the
inferior border of the tendon of the teres major muscle and is located
behind the medial border of the coracobrachialis muscle?
Correct Answer
A. Right Axillary Artery
Explanation
The given description describes the location and boundaries of the right axillary artery. It begins at the lateral border of the first rib and extends to the inferior border of the tendon of the teres major muscle. It is located behind the medial border of the coracobrachialis muscle.
14.
Extends from the inferior border of the teres major muscle... ends 1 inch below the antecubital fossa?
Correct Answer
C. Brachial Artery
Explanation
The brachial artery is the correct answer because it is the major blood vessel that extends from the inferior border of the teres major muscle and ends 1 inch below the antecubital fossa. The radial artery and ulnar artery are branches of the brachial artery, while the axillary artery and subclavian artery are located in different areas of the arm and shoulder.
15.
The Azygos Vein draining the posterior aspect of the thoracic wall and the tissues of the esophagus on the right side of the body drains into what major vessel?
Correct Answer
B. Superior Vena Cava (SVC)
Explanation
The Azygos Vein drains the posterior aspect of the thoracic wall and the tissues of the esophagus on the right side of the body. It is a major tributary of the Superior Vena Cava (SVC), which is the large vein that carries deoxygenated blood from the upper body to the right atrium of the heart. Therefore, the correct answer is Superior Vena Cava (SVC).
16.
Bone involved in the nasal septum?
Correct Answer
A. Vomer
Explanation
The bone involved in the nasal septum is the vomer. The vomer is a thin, flat bone that forms the lower part of the nasal septum, separating the left and right nasal cavities. It is located in the midline of the skull and helps to support the nasal passages and maintain their shape. The hyoid bone is not involved in the nasal septum, as it is a U-shaped bone located in the neck. The zygomatic arch is a bony arch that forms the prominence of the cheek, and the sphenoid bone is a complex bone located at the base of the skull.
17.
Heart Valve at the beginning of the Ascending Aorta?
Correct Answer
B. Aortic Semi Lunar Valve
Explanation
The correct answer is Aortic Semi Lunar Valve. The Aortic Semi Lunar Valve is located at the beginning of the Ascending Aorta. It prevents the backflow of blood from the Aorta into the Left Ventricle during diastole.
18.
Relatively fixed point of muscular attachment?
Correct Answer
B. Origin
Explanation
The term "origin" refers to the relatively fixed point of muscular attachment. It is the point where the muscle attaches to a bone or a connective tissue structure that does not move during muscle contraction. The origin is typically located closer to the midline or proximal end of the body compared to the insertion point. In contrast, the insertion is the point where the muscle attaches to a bone or a connective tissue structure that moves during muscle contraction. The belly refers to the fleshy part of the muscle, while the aponeurosis is a flat, sheet-like tendon.
19.
What Vessel is the first "Superior" artery off the Right Subclavian artery after the bifurcation of the Brachiocephalic Trunk (Inominate Artery)?
Correct Answer
A. The Right Vertebral Artery
Explanation
The right vertebral artery is the first "superior" artery off the right subclavian artery after the bifurcation of the brachiocephalic trunk. The vertebral artery runs through the transverse foramina of the cervical vertebrae and supplies blood to the brain and spinal cord. It is an important artery for the posterior circulation of the brain.
20.
Which vessel feeds the Right Facial Artery?
Correct Answer
B. The Right External Carotid Artery
Explanation
The right external carotid artery feeds the right facial artery. The external carotid artery is a major blood vessel that supplies blood to the face and neck. It branches off from the common carotid artery and gives rise to several branches, including the facial artery. The facial artery then supplies blood to the structures of the face, including the muscles, skin, and other tissues. Therefore, the correct answer is the right external carotid artery.
21.

Correct Answer
A. The Left Spermatic Vein
Explanation
The Gonadal Vein's (Spermatic and Ovarian) connect to the IVC (Inferior Vena Cava) on the Right, but on the "Left" drain into the Left Renal Vein !
