Female Genital System Flashcards
1
Q
Ovary
A
- produces the ova and ovarian hormones
1. Estrogen
2. Progesterone
2
Q
Ovary epithelium
A
- covered by a low cuboidal surface epithelium
3
Q
Ovary Tunica Albuginea
A
- lies immediately below the surface epithelium
4
Q
Ovary
A
- divided into the outer cortex and inner medulla
- > except in MARES
5
Q
Mares
A
- their ovary is the exception and the areas are reversed
- > outer medulla and inner cortex
6
Q
Ovary Outer Cortex
A
- contains numerous follicles and a corpora lutea
7
Q
Ovary Inner Medulla
A
- characterized by blood vessels, nerves and lymphatics
8
Q
Uterine Tube
A
- site of fertilization
9
Q
Uterus
A
- site of implantation
10
Q
Primordial Follicles
A
- composed of a primary oocyte surrounded by a simple squamous epithelium of follicular cells
11
Q
Primary Follicles
A
- composed of a primary oocyte surrounded by a simple cuboidal epithelium of follicular cells
12
Q
Secondary Follicles
A
- composed of a primary oocyte surrounded by a stratified epithelium termed granulosa cells which secrete zona pellucida
13
Q
Granulosa Cells
A
- secrete the zona pellucida around the plasma membrane of primary oocytes
- stratified epithelium of polyhedral follicular cells
14
Q
Theca Cells
A
- late secondary follicles
- begin to form around the granulosa cells
- a vascularized multilayer of spindle-shaped stromal cells
15
Q
Tertiary, Mature or Graafian Follicles
A
- characterized by the development of the antrum
16
Q
Antrum
A
- small fluid-filled clefts which join to form a large cavity among the granulosa cells
- contains liquor folliculi
17
Q
Primary Oocyte
A
- immediately before or just after ovulation this completes the first meiotic division to give rise to a secondary oocyte and the first polar bodies
18
Q
Cumulus oophorus
A
- antrum enlarges due to the accumulation of liquor folliculi, the oocyte is displaced and lies in a group of granulosa cells called this
19
Q
Corona radiata
A
- the granulosa cells immediately surrounding the oocyte become radially
placed and are called this
20
Q
Theca Interna
A
- have characteristic of steroid-secreting cells
21
Q
Theca Externa
A
- consists of a thin layer of loose connective tissue with fibrocytes arranged concentrically
22
Q
Ovulation
A
- rupture of the follicle and release of the oocyte
-
23
Q
Ovulation
A
- caused by luteinizing hormone (LH) and increased pressure of the antral fluid
24
Q
Follicular Atresia (degeneration)
A
- not all developing follicles terminate in ovulation
- many follicles undergo this
25
Q
Corpus Atreticum
A
- atretic follicles are reabsorbed except for small fibrous tissue scar called this
- regressed without being ovulated
26
Q
Ovaries of the Bitch and Queen
A
- there are interstitial endocrine cells
- arise from either:
- > epitheloid theca interna cells
- > hypertrophied granulosa cells of the atretic follicles
- contain lipid droplets
27
Q
Corpus Hemorrhagicum
A
- the ruptured follicle after ovulation because of the blood in the antrum
