Terminologies Flashcards
Study that deals with the internal and external structures
Vana
Gross anatomy
Macroscopic
Embryology and hisology
Microscopic
- Studies the animals structure, changes from fertilization to its maturity stage
- includes prenatal & postental
Development anatomy
- Focuses on the prenatal development of animal
- particularly on the embryonic stage
Embryology
- Process of the development of embryo to zygote
Embryogenisis
The organs grow and begins to function
Fetal stage
Haploid reproductive sex cell
Gamate
Precursor that gives rise to gametes
Germ cell
Rapidly dividing ball of cells that develop
Blastocyst
- Divides 2 identifies daughter cells
- major purpose is for growth and replace worn out cells
Mitosis
- Divides twice to produce 4 cells
- half the number of chromosome
Meiosis
Process where all develops from a less specialized to a more specialized type
Cell differentiation
- Has half the usual number of chromosomes
- (23)
Haploid cell
- ( 46 in humans )
- full number of chromosomes
Diploid cell
Inner most layer of the uterus
Endometrium
Growth of nourish
Troph
Immature
Blast
Fluid - filled sac
Cyst
The early placenta ( immature structure that will eventually nourish the embryo )
Trophoblast
Provides early nourishment to the embryo
Yolk sac
- Relating to the center
- site is umbilicus
Umbilical
Cavity lined by epithelium derived from mosederm
Coelem
Lived by 2 layers of mesodermal membrane visceral & parietal peritoneum
Peritoneal cavity
Lined by visceral & parietal pleura
Fleural cavity
Towards the head

Away from the midline
Lateral
Towards the body
Medial
In relation to the backbone
Dorsal

Palmar
Rear paw
Plantar
Close to the body or a given part
Proximal

Distal
this does divides the body into equal right and left halves
Median plane
this plane is parallel to median plane
Sagittal plane
this plane does divide the body into cranial part and caudal part
Transverse plane
