Body Cells to Four Tissue Types
- The human body has about 30 trillion cells grouped into roughly 200 functional types.
- These groups condense into four main tissue types: epithelial, connective, muscle, and nervous tissue.
Nervous Tissue and Glial Support
- Nervous tissue enables fast and direct communication using specialized neurons.
- Glial cells support and insulate neurons to maintain efficient signal transmission.
Myelin Differences Impact Regeneration
- Schwann cells in the peripheral nervous system form myelin and promote nerve regeneration.
- Oligodendrocytes in the central nervous system myelinate axons but inhibit effective nerve regeneration.
