Mapping Masculinity: Exploring the Male Reproductive System in a Mind Map
Embark on a visual journey through the male reproductive system with our comprehensive mind map.
Explore the intricate anatomy of the testes, epididymis, vas deferens, prostate gland, and urethra.
Visualize the hormonal regulation of sperm production, from the hypothalamus to the pituitary gland and testes.
Here is a detailed comprehensive mind map of the physiology topic “Male Reproductive System”:
Central Idea: Male Reproductive System
Main Branches:
- Anatomy
- Hormonal Regulation
- Spermatogenesis
- Erection and Ejaculation
- Accessory Glands and Functions
Sub-Branches:
1. Anatomy
- Scrotum
- Functions: temperature regulation, protection
- Structure: layers, cremaster muscle
- Testes
- Functions: spermatogenesis, androgen production
- Structure: seminiferous tubules, interstitial tissue
- Epididymis
- Functions: sperm maturation, storage
- Structure: head, body, tail
- Vas Deferens
- Functions: sperm transport
- Structure: muscular layer, epithelial lining
- Urethra
- Functions: sperm and urine transport
- Structure: prostatic, membranous, spongy parts
- Penis
- Functions: urination, sexual intercourse
- Structure: root, shaft, glans, foreskin
2. Hormonal Regulation
- Hypothalamic-Pituitary-Testicular Axis
- Functions: regulation of testosterone production
- Hormones involved: GnRH, LH, FSH, testosterone
- Testosterone
- Functions: spermatogenesis, secondary sex characteristics
- Regulation: negative feedback loop
- Inhibin
- Functions: negative feedback on FSH production
- Regulation: Sertoli cells
3. Spermatogenesis
- Spermatogonia
- Functions: stem cells for spermatogenesis
- Process: mitosis, meiosis
- Spermatocytes
- Functions: meiosis, genetic recombination
- Process: meiosis I and II
- Spermatids
- Functions: maturation, acrosome formation
- Process: spermiogenesis
- Spermatozoa
- Functions: fertilization
- Structure: head, neck, tail
4. Erection and Ejaculation
- Erection
- Mechanism: vasodilation, smooth muscle relaxation
- Neurotransmitters involved: NO, acetylcholine
- Ejaculation
- Mechanism: contraction of vas deferens and seminal vesicles
- Neurotransmitters involved: sympathetic nervous system
5. Accessory Glands and Functions
- Seminal Vesicles
- Functions: secretion of seminal fluid
- Composition: fructose, prostaglandins, proteins
- Prostate Gland
- Functions: secretion of prostate fluid
- Composition: citric acid, zinc, enzymes
- Urethral Glands
- Functions: secretion of mucus
- Composition: mucins, enzymes
This mind map covers the key topics related to the male reproductive system, including anatomy, hormonal regulation, spermatogenesis, erection and ejaculation, and accessory glands and their functions.
