Cells derived primarily from endoderm

Exocrine secretory epithelial cells

Barrier cells

Hormone-secreting cells

Cells derived primarily from ectoderm

Exocrine secretory epithelial cells

Hormone-secreting cells

Epithelial cells

Oral cells

Nervous system

There are nerve cells, also known as neurons, present in our human body. They are branched out. These cells make up nervous tissue. A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise.

Sensory transducer cells

Autonomic neuron cells

Sense organ and peripheral neuron supporting cells

Central nervous system neurons and glial cells

Lens cells

  • Anterior lens epithelial cell
  • Crystallin-containing lens fiber cell

Cells derived primarily from mesoderm

Metabolism and storage cells

Secretory cells

Urinary system

Reproductive system

Circulatory system

Extracellular matrix cells

Note: Cephalic connective tissue and bones are derived from the Cranial neural crest which comes from the ectoderm germ layer

Contractile cells

Blood and immune system cells

Germ cells (primordially not)

  • Oogonium/Oocyte
  • Spermatid
  • Spermatocyte
  • Spermatogonium cell (stem cell for spermatocyte)
  • Spermatozoon

Nurse cell

Interstitial cells
