Seminal Vesicle Insights: Exploring Seminal Vesicle Functionality in a Mind Map
Delve into the fascinating world of the seminal vesicle with our comprehensive mind map.
Visualize the anatomy of this gland, responsible for producing seminal fluid that nourishes and transports sperm.
Explore the hormonal regulation of seminal vesicle function, including the role of testosterone in stimulating secretion.
Understand the composition of seminal fluid, rich in fructose, proteins, and other nutrients essential for sperm survival.
Here is a detailed comprehensive mind map of the physiology topic “Seminal Vesicles”:
Central Idea: Seminal Vesicles
Main Branches:
- Structure
- Functions
- Secretions
- Regulation
- Clinical Correlations
Sub-Branches:
1. Structure
- Location
- Between bladder and rectum
- Posterior to prostate gland
- Shape
- Paired, sac-like structures
- Approximately 5 cm in length
- Wall
- Muscular layer (smooth muscle)
- Epithelial lining (columnar epithelium)
2. Functions
- Secretion of Seminal Fluid
- 60-70% of ejaculate volume
- Nutrients and energy for sperm
- Storage of Seminal Fluid
- Temporary storage before ejaculation
- Mixing with sperm during ejaculation
3. Secretions
- Fructose
- Energy source for sperm
- High concentration in seminal fluid
- Prostaglandins
- Stimulate smooth muscle contraction
- Involved in sperm transport and ejaculation
- Proteins
- Enzymes (e.g., fibrinolysin)
- Binding proteins (e.g., sex hormone-binding globulin)
- Other Components
- Citric acid, ascorbic acid, flavins, and other nutrients
4. Regulation
- Hormonal Regulation
- Testosterone: stimulates seminal vesicle growth and secretion
- Estrogen: inhibits seminal vesicle growth and secretion
- Neural Regulation
- Sympathetic nervous system: stimulates seminal vesicle contraction
- Parasympathetic nervous system: stimulates seminal vesicle relaxation
5. Clinical Correlations
- Infections
- Seminal vesiculitis: inflammation of seminal vesicles
- Epididymitis: inflammation of epididymis
- Obstruction
- Seminal vesicle stones: calcified deposits in seminal vesicles
- Ejaculatory duct obstruction: blockage of ejaculatory ducts
- Cancer
- Seminal vesicle cancer: rare, but aggressive tumor
This mind map covers the key topics related to the seminal vesicles, including their structure, functions, secretions, regulation, and clinical correlations.
