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 male and female clavicle ·          They are one of the bones used for sex determination especially in cases where only skeletal remains are available for forensic identification.     ·          Both metric (physical dimensions) and non-metric (characteristic appearance) features of the clavicle can have a decisive role in forensic identifications.    ·          The clavicle measurements or metric features include the weight (W), linear length (L), anterior curved length (ACL), posterior curved length (PCL), mid-clavicular circumference (MC), medial 2/3rd and lateral 1/3rd junction circumference (JC), and mid-clavicular anteroposterior diameter  (APD).    ·          Non-metric features include the subclavian groove, nutrient fo...
