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...

Difference between disruption and dysplasia

      Disruption : morphological alteration of already form structures due to destructive processes   . Example: amniotic band      Dysplasia : abnormal organization of cells. Example: congenital ectodermal Dysplasia    

Difference between malformation and deformation

a)       malformation : occurred during organogenesis                                 caused by environmental & / or genetics b)          Deformation : mechanical forces that mold a part of fetus. Example: clubfoot    

Difference between primary, secondary and tertiary ovarian follicle

Difference between primary, secondary and tertiary ovarian follicle  Primary follicle - follicular cell became cuboidal and zona pellucida begin to form Growing follicle: follicular cells forming the stratified layer of granulose cells and well-defined zona pellucida  Secondary follicle: fluid filled spaces developed within the granulosa cells .   Graafian follicle : single cavity formed within granulosa cell
