Webstyliform cartilage of the rodent genera Glaucomys, Pteromys, Petinomys, and Petaurista is described and compared with the cutaneous maximus of Sciurus. A pseudophyletic sequence from a non-gliding sciurid form through a primitive gliding form like Glaucomys to the well-developed gliding musculature of Petaurista is pre-sented.

WebIn the proximal row of carpals of most squirrels, the pisiform articulates only with the triquetrum, but in flying squirrels there is also a prominent articulation between the pisiform and the scapholunate, providing a more stable base for the styliform cartilage, which supports the wing tip. WebA characteristic thin membranous structure between the cutaneous and deeper muscles was observed. In addition to the direct powerful control exerted by trunk and limb movement, we suggest that indirect power conduction by this thin membranous structure may contribute to gliding membrane control. eos r6 動画オートフォーカス

Sesamoids and Morphological Variation: a Hypothesis on the

Flying squirrels are not capable of flight like birds or bats; instead, they glide between trees. They are capable of obtaining lift within the course of these flights, with flights recorded to 90 metres (300 ft). The direction and speed of the animal in midair are varied by changing the positions of its limbs, largely controlled by small cartilaginous wrist bones. There is a cartilage projection fro… WebA minute styliform cartilage, which lies in close proximity with the portio dura, on the upper part of the posterior face of the quadrate bone, represents the stylohyal, or proximal end of the hyoidean arch. The pectoral arch has no clavicle, and the coracoid has no distinct epicoraooidal element, nor any fontanelle.
