2. Longest muscle in the body of animal is

Explanation

The correct answer is Longissimus dorsi. The Longissimus dorsi is a long muscle that runs along the spine and extends from the sacrum to the base of the skull. It is one of the longest muscles in the body of an animal. It helps to extend and laterally flex the spine, and is involved in movements such as arching the back and rotating the trunk.

3. Which of the following is an aborted long bone?

Explanation

The ulna of a horse is an aborted long bone because it is a bone that is present in the early stages of development but fails to fully form. In horses, the ulna is a small, non-functional bone that is present in the forelimb but does not contribute to the overall structure or function of the limb. This is in contrast to other animals, such as ox, dog, fowl, and rabbit, where the ulna is a fully formed and functional bone.

Submit
4. Acromian process is absent in ________________________ (species).

Explanation

The acromion process is absent in horses. The acromion process is a bony projection on the scapula (shoulder blade) that provides attachment for muscles and ligaments. In horses, the scapula is relatively flat and lacks this specific projection. This anatomical difference in horses allows for greater flexibility and range of motion in the shoulder joint, which is important for their running and jumping abilities.

Submit
5. First collateral branch of aorta is

Explanation

The first collateral branch of the aorta is the coronary artery. This artery supplies oxygenated blood to the heart muscle itself. It branches off from the ascending aorta, just above the aortic valve, and then further divides into smaller branches that supply different regions of the heart. The coronary artery is essential for maintaining the proper functioning of the heart by providing it with the necessary oxygen and nutrients.

Submit
6. Supracondyloid foramen is present in the humerus of ________ (species)

Explanation

Supracondyloid foramen is a bony structure located in the humerus bone of both cats and dogs. It is a small opening that allows the passage of nerves and blood vessels. This anatomical feature is not exclusive to any particular species and can be found in both cats and dogs.

Submit
7. Rete mirabile cerebri is absent in

Explanation

The rete mirabile cerebri is a network of blood vessels found in certain animals that helps regulate blood flow to the brain. It is absent in horses, which means that they do not have this specialized mechanism for controlling blood flow in their brains.

Submit

9. Sternomandibularis division of Sternocephalicus muscle is absent in ______ species.

Explanation

The Sternomandibularis division of the Sternocephalicus muscle is not present in sheep. This muscle division is found in other species such as goats, cattle, buffalo, and dogs. However, in sheep, this particular division is absent.

Submit
10. Guttural pouches in the horse are associated with

Explanation



Guttural pouches in horses are unique anatomical structures; they are large, air-filled sacs located at the base of the skull. One of their primary functions is believed to be the cooling of arterial blood that supplies the brain. This is facilitated by the air within these sacs that can cool the blood in the nearby arteries, including the internal carotid artery, before it reaches the brain. This thermoregulatory function is critical for horses, helping to maintain optimal brain temperature during intense physical exertion or in hot environments.
Submit
11. Development of the individual is termed as __________________________

Explanation

Ontogeny refers to the development and growth of an individual organism from fertilization to adulthood. It involves the changes in structure, function, and behavior that occur during the organism's lifetime. Phylogeny, on the other hand, refers to the evolutionary history and relationships between different species or groups of organisms. Both ontogeny and phylogeny are important in understanding the development and evolution of organisms.
