Test on Comparative Thoracic Limb Vascularization

Question 1: The A. Thoracica externa supplies the pectoral muscles.

A. Ano

B. Ne

Explanation: The study materials state that A. Thoracica externa supplies 'mm. pectorales'.

Question 2: The A. collateralis ulnaris supplies the m. flexor carpi ulnaris in Bovine, Caprine, Equine, and Swine.

A. Ano

B. Ne

Explanation: The study materials state that the A. collateralis ulnaris supplies the m. flexor digitorum profundum, specifically mentioning m. flexor carpi ulnaris for Bovine, Caprine, Equine, and Swine.

Question 3: According to the study materials, which statement accurately describes the anatomical position of the A. brachialis?

A. It runs on the medial surface of the brachium, with v. brachialis and n. medianus on the craniomedial surface of the elbow joint.

B. It runs on the lateral surface of the brachium, alongside the a. profunda brachii and a. collateralis ulnaris.

C. It is located on the dorsal surface of the antebrachium, accompanied by the a. interossea communis.

D. It follows the a. axillaris caudally to the collum humeri on the medial surface of the limb.

Explanation: The study materials state: 'A. BRACHIALIS Artery runs on the medial surface of the brachium, with v. brachialis and n. medianus on the craniomedial surface of the elbow jiont'.

Question 4: Which artery is identified as the main continuation of the a. subclavia within the thoracic limb?

A. a. brachialis

B. a. thoracica externa

C. a. axillaris

D. a. subscapularis

Explanation: The study materials explicitly state that the A. AXILLARIS is the main continuation of a.subclavia.

Question 5: The v. profunda brachii is a direct main branch of the v. axillaris.

A. Ano

B. Ne

Explanation: The study materials indicate that v. profunda brachii is a branch of v. brachialis, which in turn is a main branch of v. axillaris. Therefore, v. profunda brachii is not a direct main branch of v. axillaris.
