Comparison between tract and nerve

-
  Comparison between tract and nerve Nerve Nerve contain bundle of axons (nerve fibers) in the peripheral nervous system (PNS) that transmits signals between the central nervous system (CNS) and other parts of the body. It is the most important part of peripheral nervous system Location: Peripheral nervous system. Structure: Made of axons, connective tissue layers (endoneurium: axon is surrounded by it , perineurium: bundle of axons are surrounded by it, epineurium: whole nerve trunk is surrounded by it), and blood vessels. It gets myelination by Schwann cell   Function: Carries sensory signals to the CNS (afferent) from peripheral part of body or motor signals carry from from the CNS (efferent) to target organs like skeletal muscle, cardiac muscle, smooth muscle or glands Example: Sciatic nerve, median nerve, except optic nerve (though optic nerve is technically part of CNS in develop...

Fibroblast vs fibrocyte

-
  Fibroblast  is permanent  connective tissue cell responsible for the production of the extracellular matrix (ECM) and collagen fibers which  are essential for tissue structure and repair and play a major role in wound healing. unique features of Fibroblasts : Shape and Structure :  Spindle-shaped (elongated). it contain l arge nucleus that is oval or elliptical . and c ytoplasm is abundant and basophilic (stains blue), reflecting active protein synthesis. and it has  prominent nucleolus , indicating high activity in protein synthesis. Function : it produces the structural components of the extracellular matrix like collagen , elastin , glycosaminoglycans , and proteoglycans .  In response to injury, fibroblasts proliferate and migrate to the site of injury, secreting growth factors and ECM components to promote tissue repair and fibrosis. Major producer of collagen fibers which provide tensile strength to tissues. Elastin Production : ...
