MICROSCOPIC CHARACTERISTICS OF SEROSAL,<br />
MUSCULAR AND SUBMUCOSAL LAYERS OF <strong>THE</strong><br />
LARGE INTESTINE OF <strong>PHILIPPINE</strong> CARABAOS<br />
(Bubalus bubalis)*<br />

The histological features of the submucosal, muscular, and<br />
serosal layers of the cecum, colon, and rectum of the<br />
Philippine carabao were studied using Hematoxyline<br />
staining (H&E) stained sections and various differential<br />
staining techniques. The submucosal layer consisted of a<br />
large amount of collagen fibers. A few elastic and reticular<br />
fibers were found in this layer. The submucosa appeared<br />
thickest in the cecum. Ganglion cells belonging to the<br />
submucosal plexus were plentiful. Some occurred in groups<br />
while some occurred singly. There were many blood<br />
vessels and nerves in the submucosa. The muscular<br />
layer of the large intestine consists of an inner muscular<br />
muscle layer and an outer longitudinal muscle layer. Among<br />
the three segments of the large intestine studied, the tunica<br />
muscularis was thickest in the rectum. Ganglion cells<br />
belonging to the myenteric plexus were observed in this<br />
layer and were generally located in between the muscle<br />
layers. Individual ganglion cells may be found between<br />
muscle bundles in the outer part of the inner circular muscle<br />
layer. The serosal layer was well-developed in the cecum<br />
and colon because of the accumulation of a large amount of<br />
adipose tissue between the serosa and the muscular layer.<br />
In the caudal part of the rectum, the serosal layer was<br />
replaced by an adventitial layer.<br />
Keywords: carabao, ganglion cells, large intestine,<br />

MICROSCOPIC ANATOMY OF SEMINAL VESICLE<br />
AND PROSTATE GLAND OF MALE <strong>PHILIPPINE</strong><br />
CARABAO (Bubalus bubalis L.)*<br />
F. D. B. Caoli, Student<br />
Seminal vesicle and prostate gland were collected from<br />
seven apparently healthy male Philippine carabao (Bubalus<br />
bubalis L.) between two to five years of age immediately<br />
after slaughter. The samples were processed and stained<br />
with H&E stain. The seminal vesicle of the Philippine<br />
carabao was similar with the bull. It was encapsulated by<br />
a DWFCT. The glandular epithelium was lined by simple<br />
columnar epithelium. Lipid droplets were observed in the<br />
cytoplasm of the cells. The lamina propria-tunica<br />
submucosa consisted of loose connective tissue. The tunica<br />
muscularis was thick and composed of smooth muscle<br />
fibers. The tunica adventitia consisted of loose connective<br />
tissue. The intralobular ducts were lined by simple cuboidal<br />
or stratified columnar epithelium. The body of the prostate<br />
gland was encapsulated by DWFCT with smooth muscle<br />
fibers. The glandular epithelium was lined by simple<br />
cuboidal cells. Large and small alveoli were present in the<br />
parenchyma. Prostatic concretions were observed only in<br />
larger alveoli. Intralobular ducts were lined by simple<br />
cuboidal or columnar cells.<br />
Keywords: microscopic anatomy, seminal vesicle,<br />
prostate glands, Philippine carabao, Bubalus bubalis<br />

The skin from the head, neck, dorsum, ventrum and<br />
hindlimb from five adult male Philippine carabao and<br />
Philippine Murrah crossbred were microscopically studied.<br />
The carabao skin (8.30 um) was not significantly thicker
