anatomy

Nasal cavities are separated from the oral cavity by the

Hard and soft palate

The aortic semilunar valve prevents blood from returning to the

Left ventricle

The left ventricle has the thickest wall because it pumps blood to the systemic circuit.

The thoracic duct begins as a confluence of lymph trunks in the abdomen, sometimes forming a saccular dilation referred to as the

Cisterna chyli

Inferior vena cava lies immediately to the right of the

Abdominal Aorta

The inferior mesenteric artery originates at the

L3 vertebra

The profunda brachii artery, the largest branch of the brachial artery

True

The sciatic nerve innervates

All muscles in the posterior compartment of the thigh

Femoral vein becomes the external iliac vein when it passes under the inguinal ligament to enter the abdomen

True

The axillary artery is separated into 3 parts by pectoralis major

False

Atrial septal defect

Malformation resulting from incomplete closure of the foramen ovale (foramen secundum).

Axillary nerve

Innervates the deltoid and teres minor muscles.

Dorsalis pedis artery

Artery that continues from the anterior tibial artery and starts at the ankle joint.

Radial and Ulnar artery

Major branches into which the brachial artery divides at the apex of the cubital fossa.

Cephalic vein

Superficial vein draining the lateral and posterior parts of the hand, forearm, and arm.

Common palmar digital arteries

Provide the principal blood supply to specific fingers.

Deep artery of the penis

Supplies the crus and corpus cavernosum of the penis.

External pudendal arteries

Originate from the femoral artery.

Inferior vesical artery

Supplies the bladder, ureter, and seminal vesicle in men.

Serous membrane

The type of membrane that surrounds the lungs.

Pleural cavity

The space between the parietal and visceral pleura.

Arytenoid cartilage

Cartilage to which vocal cords are attached.

Choanae

Oval-shaped openings between the nasal cavity and nasopharynx.

6th, 8th, 10th ribs

Inferior boundary of the visceral pleura approximated by a line from the midclavicular line to the vertebral column.

Thoracic duct

Drains lymph to the junction of the left subclavian and left internal jugular vein.

Superior mesenteric artery

Gives rise to middle colic, right colic, and ileocolic arteries.

Left colic artery

Mostly supplies the descending colon.

Splenic vein

In most cases, drains blood from the inferior mesenteric vein.

Nasal septal cartilage

Not a part of the larynx cartilages.

Arytenoid cartilages

Cartilage with muscular process and vocal process.

VIII

Inferior margin of the lung crosses rib VIII during quiet respiration in the midaxillary line.

Horizontal fissure

Separates the superior from the middle lobe of the lung.

3

Number of lobar bronchi in the right lung.

Right main bronchus

Wider and more vertical than the left main bronchus.

Superior Vena Cava

Not a part of the hilum.

Femoral artery

External iliac artery becomes this as it passes under the inguinal ligament.

Deep artery of the thigh

Has lateral and medial circumflex femoral branches and three perforating branches.

Popliteal artery

Originates anterior and posterior tibial arteries.

Contains the SA node

Importance of the right atrium in a case of chronic atrial fibrillation.

Left recurrent laryngeal nerve

Found in the superior mediastinum.

Coronary arteries

Not found in the superior mediastinum.

Receives the accessory hemiazygos vein

Incorrect statement regarding the left brachiocephalic vein.

Attach aorta to pulmonary artery

Function of the ligamentum arteriosus.
