About Testis Diagram Class 12

The testis is where sperm cells and the hormone testosterone are produced. This model labels its internal tubules and structures involved in that process.

Why It's Important

  • Produces sperm needed for reproduction
  • Produces testosterone, driving male development
  • Central to puberty and fertility
  • Continuously active throughout adult life

Observation Points

  • Locate the tightly coiled seminiferous tubules
  • Identify where testosterone is produced
  • Trace the path sperm take toward the epididymis
  • Consider why the testis sits outside the body

Learning Objectives

  • Identify the main parts of the testis
  • Explain how sperm and testosterone are produced
  • Describe the path sperm take after production
  • Understand the testis's role in puberty

Summary

The testis continuously produces sperm and testosterone inside its tightly coiled tubules, driving both reproduction and male development.

Main Parts

PartFunction
Seminiferous TubulesCoiled tubes where sperm are produced
Leydig CellsProduce testosterone
EpididymisStores and matures sperm
ScrotumHouses and regulates temperature of the testis

How It Works

Sperm cells develop inside the seminiferous tubules
↓
Leydig cells release testosterone into the blood
↓
Mature sperm move into the epididymis
↓
Sperm are stored until needed for reproduction
