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 greater omentum and lesser omentum

Difference between greater omentum and lesser omentum Greater omentum Lesser omentum The greater omentum is a large apron-like fold of  peritoneum that hangs down from the greater curvature of stomach. It extends from the greater curvature of the stomach, passing in front of the small intestines and doubles back to ascend to the transverse colon before reaching to the posterior abdominal wall The lesser omentum ( small omentum or gastrohepatic omentum ) is the fold of  peritoneum that attached with lesser curvature of the stomach. it extends from the liver to the lesser curvature of the stomach (hepatogastric ligament) and the first part of the duodenum (hepatoduodenal ligament). It has four layers It has two layers It has three subdivision Gastrophrenic ligament—extends to the underside of the left dome of the diaphragm Gastrocolic ligament—extends to the transverse colon(occasionally on its ow...

Difference between medial and lateral longitudinal arches of foot

-
Difference between medial and lateral longitudinal arches of foot Medial longitudinal arch Lateral longitudinal arch It is made up by the calcaneus, the talus, the navicular, the three cuneiforms (medial, intermediate, and lateral), and the first, second, and third metatarsals It is composed of the calcaneus, the cuboid, and the fourth and fifth metatarsals The medial arch is higher than the lateral longitudinal arch. It   is lower than the medial   longitudinal arch. It is formed by more bones and joints It is formed by less bone and joint It is more mobile It is less mobile It acts as shock absorber It commonly bears body weight Its summit is at the superior articular surface of the talus The peak of the lateral longitudinal arch is located at the level of articular facets on the superior outermost layer of the calca...

Difference between cytotrophoblast and syncytotrophoblast  Cytotrophoblast Syncytotrophoblast Inner layer of trophoblast Outer layer of trophoblast It is the trophoblastic stem cells It is not stem cells It has important role in implantation It invades the wall of uterus It is not establishes nutritional supply between mother to fetus It establishes nutritional supply between mother to fetus It can differentiated It is terminally differentiated cell This tissue   is formed by individual cell This tissue is specialized and it is   multinucleated with no individual cell This layer does not produce hormones The syncytiotrophoblast secretes progesterone and leptin in addition to human chorionic gonadotropin (hCG) and human placental lactogen (HPL); hCG prevents degeneration of the corpus luteum.
