Abstract


This study was performed on the tendons and muscles of two Anatolian bobcats (Lynx lynx). The research materials were donated by Republic of Turkey Ministry of the Forestry and Water Affairs Sivas Branch Manager. To achieve this objective, dissection and radiography were applied to two dead specimens. Digit I is radiographically rudimentary in the forepaw. The muscles and tendons of the forepaw in the bobcat are located in the cranial and caudal aspect of the antebrachium, the central manus and hypothenar region. The extensor muscles are situated on the cranial aspect of the antebrachium, while the flexor muscles are located on the caudal aspect of the antebrachium. The m. extensor carpi radialis in the extensor group has long and short portions; the m. extensor digitorum lateralis et communis give rise to tendons associated with fingers; the fascia covering the muscles emerges on the lateral and medial border of the m. extensor digitorum lateralis. The m. flexor digitorum superficialis et profundus lie on the caudal aspect of the antebrachium; the superficial digital flexor tendons give rise to the origin of the bellies of the m. flexor digitorum brevis; the m. flexor digitorum profundus form a stout tendon from which the mm. lumbricales originate on the palmar aspect of carpal joints; the tendon of the muscle perforates the tendon of the m. flexor digitorum superficialis. The mm. flexores digitorum profundi breves in the central manus group consist of the lateral and medial portions and insert on the palmar aspect of each proximal phalanx associated with the fingers. Other muscles in the group, adductores digitorum, end to those in the fingers.

Key words: Anatolian bobcat (Lynx lynx); forepaw; muscles; tendons; anatomy

 

MAKROSKOPSKA ŠTUDIJA KIT IN MIŠIC SPREDNJE ŠAPE PRI RISU (Lynx lynx)

Povzetek: V raziskavi smo proučili kite in mišice sprednje šape pri dveh risih (Lynx lynx). Material za raziskavo je darovalo Ministrstvo za gozdarstvo in vode Turčije. Na dveh kadavrih je bila izvedena radiografija in sekcija. Radiografija je pokazala, da je prvi prst sprednje šape rudimentaren. Mišice in kite sprednje šape se pri risu nahajajo v kranialnem in kavdalnem področju podlahti, centralnega dela dlani in na področju mišic, ki premikajo 5. prst. Mišice iztegovalke se nahajajo na sprednjem delu podlahti, medtem ko so mišice upogibalke nameščene na kavdalnem področju podlahti. Ena izmed mišic iztegovalk m. extensor carpi radialis ima dolge in kratke odseke; iz mišice m. extensor digitorum lateralis et communis izhajajo kite za prste; fascija, ki pokriva mišice pa se začne na lateralnem in medialnem področju mišice m. extensor digitorum lateralis. Mišica m. flexor digitorum superficialis et profundus leži na kavdalnem področju podlahti; iz površinskih tetiv digitalnega fleksorja pa izhaja trebuh mišice m. flexor digitorum brevis; m. flexor digitorum profundus tvori močno tetivo, iz katere mm. lumbricales izvirajo na palmarnem področju karpalnih sklepov. Tetiva mišice perforira tetivo mišice m. flexor digitorum superficialis. Mišice mm. flexores digitorum profundi v osrednji skupini mišic področja dlani so sestavljene iz lateralnih in medialnih delov in se nahajajo na palmarnem področju vsake proksimalne prstnice in so povezane s prsti. Druge mišice v skupini mm. adductores digitorum, se končajo na koncih istih prstov.

Ključne besede: ris (Lynx lynx); sprednja šapa; mišice; kite; anatomija
