Sperm

Male Reproductive System

Germ cell/basic functional unit of the male reproductive system

Sperm

Fundamentals:

Functions

• Fertilize the egg to create an organism
• Normally haploid

Anatomy of Sperm:

• Acrosome - digestive enzymes
• Head - contains nucleus and DNA
• Midsection - contains mitochondria
• Tail - flagella powered by mitochondria

Classification of Sperm

Basement Membrane of Seminiferous Tubules

• Spermatogonia
  • Mitosis
• Primary Spermatocytes
  • First Meoitic Division
• Secondary Spermatocytes
  • Second Meoitic Division
• Spermatids
  • Transformation Event
• Spermatozoa - Lumen

Lumen of Seminiferous Tubules

Chemicals:

• Acrosome digestive enzymes

Concept:

• Germ Cells
• Spermatogenesis
  • Process requires lower temperature from the body
  • Orientation cells from basement membrane to lumen
  • Cell division of sperm cells
    • Math behind the cell divisions
• Hormonal control of Sperm Production
  • Spermatogenic
• Secondary Sex Characteristics in Males
• Mechanisms of Deliver

Terminology:

• Haploid - Poidy/Genetics
• Transformation Event: spermatids initially formed are all connected to each by cytoplasmic bidges
