MAGNETIC RESONANCE IMAGING OF THE NORMAL FELINE BRAIN

The Purpose of this study was to produce an atlas of magnetic resonance images (MRI) of the feline brain and associated structures. The head of nine clinically normal cats was imaged in 2 or 3 anatomic planes and 3 sets of technical parameters resulting in T1, T2, and proton-weighted density images. Images were compared with anatomic texts, with preserved and sectioned feline cadaver heads, with preserved and sectioned feline brains, and with intact, sectioned, and disarticulated feline skulls for aid in identification of structures. Anatomic and neuroanatomic structures are identified on selected images in different planes as reference for MR morphology of the normal feline brain and related structures.     

The lumbosacral Plexus of the Barn Owl (tyto alba): Formation,branches and distribution

The aim of the present study is to reveal the anatomical structure of lumbosacral plexus of barn owl. Six barn owls were included in the study. Nerves originating from plexus were dissected individually, and findings of innervation areas of nerves were determined. Lumbosacral plexus of barn owl was observed to be formed by ventral rami of ten synsacral spinal nerves. It was found that while the r. cutaneus femoris lateralis, the n. obturatorius, the n. coxalis cranialis, the r. cutaneus femoris medialis, the n. cutaneus femoris cranialis and the n. femoralis originated from the lumbar plexus, the n. isciofemoralis, the n. cutaneus femoris caudalis, the n. coxalis caudalis and the n. ischiadicus originated from the sacral plexus. Consequently, when the results of the study were compared with information of different avian species, it was observed that differences focused on the formation of the lumbar and sacral plexuses and innervation level of digits.

Anatomical description of the origin and distribution of the lumbosacral plexus in one puma (Puma concolor)

Wild felids often suffer spinal and limb disorders; however, their nervous system anatomy is poorly studied. Herein, the lumbosacral plexus (Plexus lumbosacralis) of an adult puma and the motor and sensitive innervation of the pelvic limb is described. We found anatomical similarities to other felids, but also some differences. Branches L4-S3 form the lumbosacral plexus (Plexus lumbosacralis) in the puma. The femoral nerve (N. femoris) arises from the union of L4-L5, while in other felids, it is formed by L5-L6. Unlike in the cat, the sartorius muscle receives branches from the saphenous (N. saphenous) and femoral nerves (N. femoris), and the lateral head of the gastrocnemius and superficial digital flexor muscles are innervated by a branch of the soleus muscle.     

A Macroscopic Investigation of the Nerves to the Eye and Ocular Annexes in the Van Cat

The orbital nerves were examined grossly in eight adult Van cats from either sex. The optic nerve, in a sigmoid curl, reached the eyeball after coursing between the retractor bulbi and medial rectus muscles. The oculomotor nerve gave off dorsal and ventral branches between the retractor bulbi and lateral rectus muscles. The ciliary ganglion was located on the lateral subbranch of the ventral branch of this nerve in all materials. There were short ciliary nerves originated from the ciliary ganglion in all the materials observed. The lacrimal nerve was a branch of the maxillary nerve.
