IDENTIFICATION AND COMMENT ON PERMANENT SLIDES OF MAMMALS

Aim: To observe and comment on anatomical details of certain organs/structures in mammals.

A. Slide showing T.S of mammalian testis.

Picture
Comments

  1. Seminferous tubules are numerous and somewhat rounded or oval in section, embedded in connective tissue mass.
  2. Special large sertoli cells are present on which sperm are attached in clusters
Picture

B. Slide showing T.S of mammalian ovary
Picture
Comments
  1. It is bounded by germinal epithelium flowed by thick layer of fibrous tissue, the tunica albuginea.
  2. Stroma is formed of connective tissue, interspersed with blood vessels, nerve fibers and spindle shaped cells.
  3. A primary follicle consists of a central ovum surrounded by a group of follicular cells.
Picture

C. Slide showing T.S of blastula
Picture
Comments-
  • Hollow ball of cells.
  • Cavity blastocoel is visible.
  • Inner cell mass seen towards a side.

IDENTIFICATION OF PATHOGENS IN BLOOD

Aim: To study and identify common diseases causing protozoans like Entamoeba and Plasmodium through permanent slides.
A. Slide showing Entamoeba histolytica
Picture
Systematic position:
(to be written on blank page)
Phylum - Protozoa
Class - Rhizopodea or Sarcodina
Genus- Entamoeba

Comments:
1. It usually measures from between 12 and 20 microns.
2. The cytoplasm usually contains little debris with a fine outer membrane.
3. They are smooth without much pseudopodia    
Picture
B. Slide showing Plasmodium sps. (Malarial parasite)
Picture
Identification:
RING STAGE-
  • Plasmodium spp. rings have large chromatin dots.
  • Cytoplasm ameboid in trophozoite.
  • The enlarged size of the infected RBCs.
GAMETOCYTES-
  • Plasmodium spp gametocytes are round to oval with scattered  pigment.
  • They almost fill the red blood cell.
