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 cervical, thoracic and lumbar vertebra Topic Cervical Thoracic Lumbar body 1. Smallest of all vertebra 2.Transverse measurement is greater than anterior posterior measurement 3.Superior surface is concave 1.Body is heart shaped 2.Anterior posterior measurement is greater than the transverse measurement 3. body bears costal facet   1.Body is big size and kidney shaped 2. Transverse measurement is greater than anterior posterior measurement 3. body is thick in front than behind Transverse process 1.It is pierce by foramen transversarium 2.It has anterior and posterior root which is connected by costo-transverse bar 1. Big size face laterally and backwards   2. Each process bears a facet which articulate with numerically corresponding tubercle of rib 1. Thin and elongated 2. An accessory process is present a...

Gastroschisis vs omphelocele Gastroschisis omphelocele   Incidence 1: 10,000 Incidence 2.5: 10,000 M:F: 1:1 M:F: 1.5:1 Ventral abdominal wall defect resulting from a lack of closure of the lateral body wall folds in the abdominal region resulting in protrusion of intestines and sometimes other organs through the defect   lateral to the umbilicus usually on the right   Ventral abdominal wall defect caused by failure of physiologically herniated loops of bowel to return to the abdominal   cavity in the 10 th week It is developed earlier than the omphelocele 3 rd to 4 th week of gestation when lateral folds of embryonic disc l fail to fuse together Physiological umbilical herniation of intestinal loops develops at 6 th week of intrauterine life and normally it start to return at 10 th week of intrauterine life. In omphelocel...
