Hi! If you wish to know topics like this on big cats, there are more than enough threads on Pantherine felids (big cats). Feel free to ask your question there! As for your question, I hope this helps!

Muscular anatomy of the forelimb of tiger (Panthera tigris) LINK

Abstract

Dissection reports of large cats (family Felidae) have been published since the late 19th century. These reports generally describe the findings in words, show drawings of the dissection, and usually include some masses of muscles, but often neglect to provide muscle maps showing the precise location of bony origins and insertions. Although these early reports can be highly useful, the absence of visual depictions of muscle attachment sites makes it difficult to compare muscle origins and insertions in living taxa and especially to reconstruct muscle attachments in fossil taxa. Recently, more muscle maps have been published in the primary literature, but those for large cats are still limited. Here, we describe the muscular anatomy of the forelimb of the tiger (Panthera tigris), and compare muscle origins, insertions, and relative muscle masses to other felids to identify differences that may reflect functional adaptations. Our results reiterate the conservative nature of felid anatomy across body sizes and behavioral categories. We find that pantherines have relatively smaller shoulder muscle masses, and relatively larger muscles of the caudal brachium, pronators, and supinators than felines. The muscular anatomy of the tiger shows several modifications that may reflect an adaptation to terrestrial locomotion and a preference for large prey. These include in general a relatively large m. supraspinatus (shoulder flexion), an expanded origin for m. triceps brachii caput longum, and relatively large m. triceps brachii caput laterale (elbow extension), as well as relatively large mm. brachioradialis, abductor digiti I longus, and abductor digiti V. Muscle groups that are well developed in scansorial taxa are not well developed in the tiger, including muscles of the cranial compartment of the brachium and antebrachium, and m. anconeus. Overall, the musculature of the tiger strongly resembles that of the lion (Panthera leo), another large-bodied terrestrial large-prey specialist.

Advice for all forum users, especially new ones:

If you wish to know something or have questions on a certain animal (lets say Big Cats as they are the most popular) check the threads on them. Pantherine felids have their own dedicated subforums and multiple threads. Dont make a new thread for a single question or even information for that matter. Thank you and Enjoy reading WildFact!

I suggest @BA0701 or any other MOD to take these posts to any of the tiger threads you seem relevant.

Moved to the appropriate thread, and other moderation actions taken.
