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 alar plate and basal plate of the mantle layer of neural tube

-
  Difference between alar plate and basal plate  of the mantle layer of neural tube Alar plate Basal plate The  alar plates  (or  alar lamina ) is a neural structure in the embryonic nervous system. Sensory area in the dorsal region of the spinal cord and brain In the developing  nervous system , the  basal plate  is the region of the  neural tube  ventral to the  sulcus limitans they develops from dorsal aspect of mantle layer of neural tube they develops from ventral   aspect of mantle layer of neural tube Functional components deal by alar plate :    Cells within the alar plate develop into afferent and interneurons. The alar plate further develops general sensory afferents (GSA) innervating the skin, special sensory afferents (SSA) innervating the branchial arch derivatives, and visceral sensory af...

Difference between granular, agranular, homotypical and heterotypical cortex

-
  Difference between granular, agranular, homotypical and heterotypical cortex or different cytoarchitectural composition of cerebrum Classification Based on Cytoarchitecture (Cellular Composition) Granular Cortex (Koniocortex) Description : it is well-developed layer IV (internal granular layer), rich in neuron , known as small granular (stellate) cells. Function : it is done sensory processing (receives input from the thalamus). Example : Primary somatosensory cortex (Brodmann areas 3, 1, 2). Primary visual cortex (Brodmann area 17). Primary auditory cortex (Brodmann areas 41, 42). Agranular Cortex Description : it is poorly developed or absent layer IV, contain neuron with large size known as   large pyramidal cells in layer V. Function : it controls motor function   (sends output to spinal cord and brainstem). Example : ...

Difference between codon and anticodon

  Difference between codon and anticodon <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js?client=ca-pub-3738618711723990"      crossorigin="anonymous"></script> Codon Anticodon Codons are trinucleotide units that present in mRNA and codes for a particular amino acid in protein synthesis. Anticodon is trinucleotide units that present in tRNA. It is complementary to the codons in mRNA. Codons transfer the genetic information from the nucleus to the ribosomes where protein synthesis takes place. The anticodons are referred to as the link between the nucleotide sequence of the mRNA and the amino acid sequence of the protein. The codons are present in DNA and RNA. The anticodons are present in the anticodon arm of tRNA. One mRNA comprises a no. of codons. One tRNA contains the only anticodon. ...

Difference between renal sinus and renal hilum

-
  Difference between renal sinus and renal hilum Renal sinus Renal hilum •       The renal sinus is a cavity within the kidney which is occupied by the renal pelvis, renal calyces, blood vessels, nerves and fat   •       The renal hilum is the entry and exit site for structures servicing the kidneys: vessels, nerves, lymphatics, and ureters.

Difference between renal lobe and renal lobule

-
 Difference between renal lobe and renal lobule  Lobe of kidney Lobule of kidney Each medullary pyramid and the associated cortical tissue at its base and sides (one half of each adjacent renal column) constitutes a lobe of the kidney. The lobes of the kidney are further subdivided into lobules consisting of a central medullary ray and surrounding cortical material . the medullary ray containing the collecting duct for a group of nephrons that drain into that duct constitutes the renal secretory

Difference between anterior branch and posterior branch of axillary nerve

-
Difference between anterior branch and posterior branch of axillary nerve Anterior branch of axillary nerve posterior branch of axillary nerve ·          The  anterior branch  (upper branch) winds around the surgical neck of the humerus beneath the deltoid muscle, with the posterior humeral circumflex vessels. It continues as far as the anterior border of the deltoid to provide motor innervation. The anterior branch also gives off a few small cutaneous branches, which pierce the muscle and supply in the overlaying skin. ·          .   The  posterior branch  (lower branch) supplies the teres minor and the posterior part of the deltoid The posterior branch pierces the deep fascia and continues as the superior (or upper) lateral cutaneous nerve of arm, which sweeps around the post...
