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 Gynaecoid pelvis, Anthropoid pelvis, Android pelvis & Platypelloid pelvis

  Difference between Gynaecoid pelvis, Anthropoid pelvis, Android pelvis & Platypelloid pelvis The articulated skeleton of pelvis is four main types based on its shape and dimensions. Pelvic types influence childbirth and the ease of vaginal delivery. 1. Gynaecoid Pelvis which is most Favorable for Vaginal Delivery   Most common type (50%) , typical of females. Best suited for childbirth due to its round shape and spacious all dimensions of pelvis . 🔹 Shape : Oval (transversely rounded). 🔹 Inlet : Spacious, wide, and circular. 🔹 Sacrum : Well-curved, allowing smooth fetal descent. 🔹 Subpubic Angle : >90° (wide) than male type of pelvis . 🔹 Ischial Spines : Less prominent and everted  allowing more space. 🔹 Outlet diameter is large and well-adapted for vaginal birth. ⭐ Best pelvis for normal vaginal delivery (NVD). 2. Anthropoid Pelvis (Common in Some Populations) More common in African and some Asian women (25%). It is also fvorable for vag...
