There are many different types of cells in the human body.

Cells derived primarily from endoderm[edit]

Exocrine secretory epithelial cells.[edit]

Barrier cells[edit]

Hormone-secreting cells[edit]

Cells derived primarily from ectoderm[edit]

Exocrine secretory epithelial cells[edit]

Hormone-secreting cells[edit]

Epithelial cells[edit]

Oral cells[edit]

Nervous system[edit]

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[edit]

Autonomic neuron cells[edit]

Sense organ and peripheral neuron supporting cells[edit]

Central nervous system neurons and glial cells[edit]

Lens cells[edit]

Cells derived primarily from mesoderm[edit]

Metabolism and storage cells[edit]

Secretory cells[edit]

Barrier cells[edit]

Urinary system[edit]

Reproductive system[edit]

Circulatory system[edit]

Extracellular matrix cells[edit]

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

Contractile cells[edit]

Blood and immune system cells[edit]

Germ cells (primordially not)[edit]

Nurse cell[edit]

Interstitial cells[edit]
