VS331: Module 40: Female Reproductive System

Function: Carry the ova from the ovary to the uterus

1. Infundibulum - Funnel shape, has fibriae, prevents ovum from escaping into the abdominal cavity

2. Ampulla - Long tube, Site of fertilization, suspended my mesosalpinx

3. Isthmus - Short, leading to the uterus

4. Uterotubal Junction - Opening, lies in uterine wall

Describe the function of the oviducts, list its 4 parts, & list some characteristics

Oviduct

1. Cilia

2. Lamina propria

- Tunica mucosa: simple columnar epithelium w/ciliated & non ciliated cells

- Lamina propria-submucosa: nonglandular loose connective tissue

- No lamina muscularis

Tunica muscularis: Thick w/2 layers of smooth muscle.

- Tunica serosa: Dense CT

Identify the organ & #1 & 2. List the tunica and their characteristics.

1. Transport of spermatoza - Uterine contraction

2. Development of embryo & fetus - Via placenta

List a couple functions of the uterus

1. Body - Site of fetal development

2. Cervix - Contains internal and external os, separates the external body from the uterus

List and describe the two parts of a simple uterus

1. Perimetrium - Tunica serosa

2. Myometrium - Tunica muscularis

3. Endometrium - Tunica mucosa & lamina propria-submucosa

Identify #1 - 3; list the name and which tunic they are associated with

Black arrows = Uterine glands: Secrete mucus, lipids, glycogen & proteins.

1. Endometrium

2. Stratum functionalis - Sloughed off at menstration

3. Stratum basale - Source for regeneration of stratum functionale

- Estrogen & Progesterone prepare the endometrium for potential implantation of a fertilized ovum

Identify the black arrow & # 1 - 3. What hormones cause changes in the layers?

Vagina

Function: Site of sperm deposition

Tunica mucosa

- Lamina epithelialis mucosae: Nonkeratinized stratifed squamous epithelium

- Lamina propria-submucosa: Loose CT

Tunica muscularis - 2 to 3 layers of smooth muscle

Tunica adventita on caudal end

Tunica serosa on cranial end

Identify the organ, its function & list the tunica and their characteristics

1. Vestibule - contains vestibular glands (mucous glands)

2. Clitoris - Contains cavernous/erectile tissue

3. Labia - Typical skin, primates have 2 pairs of folds

List the 3 parts that make up the vulva

Mammary gland

1. Alveoli

- Lined with simple columnar or cuboidal epithelium

- Secretes via the apocrine method

2. Lactiferous ducts

3. CT stroma

4. Glands - made up of alveoli

Identify the organ & 1-4. Describe the epithelium lining #1 and its method of secretion

Inactive, or nonlactating glands have more CT stroma than glandular tissue. More adipose & leukocytes may be present in significant amounts

Describe the difference between the glands seen above and active glands
