Test on Veterinary Aorta and Arterial Branches

Question 1: In ruminants, the arcus aortae directly gives rise to the truncus bicaroticus.

A. Ano

B. Ne

Explanation: According to the study materials for Eq (Equine) and Ru (Ruminants), the arcus aortae gives rise to the truncus brachiocephalicus and the a. subclavia sinistra. The truncus bicaroticus is not listed as a direct branch from the arcus aortae for ruminants in the provided main branching structure.

Question 2: According to the provided study materials, which of the following arteries is a listed branch of the A. subclavia?

A. truncus costocervicalis

B. a. coronaria dextra

C. a. vertebralis

D. a. carotis communis

Explanation: The study materials explicitly list "truncus costocervicalis" and "a. vertebralis" as branches of the A. subclavia. "A. coronaria dextra" is a branch of the aorta ascendens, and "a. carotis communis" branches from the arcus aortae or truncus brachiocephalicus, not directly from the A. subclavia.

Question 3: The r. ascendens is a branch of the a. cervicalis superficialis.

A. Ano

B. Ne

Explanation: The study materials list r. ascendens as a branch of a. cervicalis superficialis, supplying the m. trapesius cervicis.

Question 4: The a. thoracica interna (11) is depicted as originating directly from the arcus aortae (1).

A. Ano

B. Ne

Explanation: According to the diagram 'Dog thorax arteries' (img-0.jpeg), the a. thoracica interna (11) originates from the a. subclavia sinistra (3), not directly from the arcus aortae (1).

Question 5: According to the study materials, which artery shares a common campaign trunk with the a. cervicalis profunda in ruminants?

A. a. vertebralis

B. a. intercostalis suprema

C. a. scapularis dorsalis

D. a. thoracica interna

Explanation: The study materials state: 'the campaign trunk of the a. scapularis dorsalis and a. cerviculus profunda in ruminants'.
