“…The distribution of N. plantaris medialis and N. plantaris lateralis in the Bengal tiger was like that reported in the lion (Medina Puentes et al, 2014) and the puma. Both branches were observed to be covered by M. flexor digitorum superficialis or M. flexor digitorum brevis, which exhibited significant development, consistent with previous studies conducted on the lion (Barone, 1967) and the puma (Caro‐Munizaga & Concha‐Albornoz, 2014).…”

The Bengal tiger (Panthera tigris tigris) is a species belonging to the Felidae family. In Argentina, tigers are currently only found in captivity. The longevity of individual animals in human‐controlled environments depends on proper management and practices that prioritize animal welfare. Regular veterinary care is essential to maintain optimal health conditions. Professionals must have a comprehensive understanding of the anatomy and physiology of tigers to effectively perform medical procedures and administer treatments. The study described in the text focuses on the trajectory and distribution of nerves in the pelvic limb of a Bengal tiger specimen, providing detailed dissection findings. The results revealed that the lumbosacral plexus is formed from the ventral rami of the LIV, LV, LVI, LVII, SI, SII and SIII nerves. Among the observations to highlight is the great development of the nerves N. cutaneus femoris lateralis and N. cutaneus femoris caudalis some differences were observed in the distribution of the N. femoralis and N. obturatorius; the N. ischiadicus, together with its division into the fibularis communis and tibialis nerves, showed the same configuration observed in other cats. Finally, it was observed that the nerves N. gluteus cranialis and N. gluteus caudalis also originated from the truncus lumbosacralis. The similarities and differences with studies carried out on other cats are relevant and provide anatomical data for medical procedures in the Bengal tiger.

“…Such information gaps force the clinical practitioner to extrapolate the puma anatomy from that of the domestic cat (Concha et al, 2004). Nevertheless, there are anatomical studies in the puma, such as the masticatory apparatus in young and adult animals (Biknevicius, 1996), the appendicular (Pacheco & Zapata, 2017) and axial skeleton (Zapata & Pacheco, 2019), the cranial morphology (Sims, 2012), the intrinsic musculature of the thoracic limb (Concha et al, 2004) and of the pelvic limb (Caro‐Munizaga & Concha‐Albornoz, 2014), a description of the nerves of the forearm and hand (Sanchez et al, 2013) and, a description of the lumbosacral plexus (Londoño‐Osorio et al, 2020). The knowledge of the brachial plexus anatomy is essential for clinical diagnosis and surgical interventions after traumatic lesions, which are not uncommon in wild felids (Aubert et al, 2004).…”

The knowledge of the anatomy of the brachial plexus in animals is of great importance due to its applicability in clinical, diagnostic and surgical procedures. The objective of the present study was to describe the anatomy of the brachial plexus in the puma. The results demonstrate a broad anatomical similarity with other felines; however, some differences were found. The formation of the brachial plexus in the puma occurred from the ventral interconnections of the last three cervical nerve segments and the first thoracic (C6, C7, C8 and T1). The N. suprascapularis emerges from C6, innervating the M. supraspinatus, the M. infraspinatus, and also the M. cleidobrachialis, the latter by a smaller branch. We found an independent branch emerging from C6 that innervates the M. serratus ventralis cervicis, not reported in other species. The innervation territory of the N. axillary includes the M. cleidobrachialis. The M. teres major was not innervated by the axillary nerve, but by an entirely independent branch that came from C6 and C7, and that also innervated the most caudal part of the M. subscapularis.

“…In addition, they also had a strong joint with the tail, with wider areas of major sacrococcygeal muscles, most probably due to either a very mobile and/or long tail. The median crest exhibits a larger surface, which means that the longissimus muscle system has a larger attachment area, conferring a high ability of vertebral column stabilisation (Done et al, 2010;Caro-Munizaga and Concha-Albornoz, 2014). However, it is striking that those species that score positively on the PC1 are the canids, and especially the grey fox (U. cinereoargenteus), and the hyaenids, as well as the herpestids and procyonids (Figure 6a).…”

“…In contrast, those species with negative scores on the first eigenvector possess: (a) smaller attachment areas for the sacrocaudal muscles and the longissimus muscles; (b) areas of attachment for the rest of the muscles on the lateral crest antero‐posteriorly long but medio‐laterally narow; and (c) larger sacrocaudal and sacrolumbar articulations (Figure 6b), resulting in a narrower articulation with the tail and the presacral column. In general, most of the muscle insertions were not reduced, except for those belonging to muscles that determine the tail movement and the presacral column stabilisation (Done et al ., 2010; Caro‐Munizaga and Concha‐Albornoz, 2014). In fact, those species that possess very short tails in relation to their bodies such as ursids, phocids and otarids, score negatively on the PC1, and plot in the left part of the morphospace depicted in Figure 6a.…”

“…The muscles inserted in the sacrum are as follows: the longissimus system, multifidus muscles, intertransverse muscle, piriform muscle, costalis lumborum and gluteus maximus (Figure 2, after Done et al ., 2010; Caro‐Munizaga and Concha‐Albornoz, 2014). The piriform muscle (Figure 2a) is the extensor of the hip articulation and its origin is the latero‐caudal part of the sacrum, it inserts in the greater trochanter of the femur.…”

Morphological evolution of the carnivoran sacrum

et al. 2020

The sacrum is a key piece of the vertebrate skeleton, since it connects the caudal region with the presacral region of the vertebral column and the hind limbs through the pelvis. Therefore, understanding its form and function is of great relevance in vertebrate ecomorphology. However, it is striking that morphometric studies that quantify its morphological evolution in relation to function are scarce. The main goal of this study is to investigate the morphological evolution of the sacrum in relation to its function in the mammalian order Carnivora, using three-dimensional (3D) geometric morphometrics. Principal component analysis under a phylogenetic background indicated that changes in sacrum morphology are mainly focused on the joint areas where it articulates with other parts of the skeleton allowing resistance to stress at these joints caused by increasing muscle loadings. In addition, we demonstrated that sacrum morphology is related to both the length of the tail relativised to the length of the body, and the length of the body relativised to body mass. We conclude that the sacrum in carnivores has evolved in response to the locomotor requirements of the species analysed, but in locomotion, each family has followed alternative morphological solutions to address the same functional demands.
