Study Notes
Sertoli Cells
- Also known as Supporting or Nursing cells
- Shape: Tall irregular cells
- Location: Extend among the spermatogenic cells from the basal lamina to the lumen
Peritubular Tissue
- Consists of 3-5 layers of myoid cells
- External to the basal lamina
Cytoskeleton
- Composed of microfilaments and microtubules
Test your knowledge of the structure of seminiferous tubules, including the different types of cells and tissue layers. Learn about the roles of Sertoli cells, basal lamina, and peritubular tissue. Identify the components that make up these vital structures in the male reproductive system.
