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...

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.

The codon is complementary to the nucleotide triplet of a gene in DNA.

it is complementary to the respective codon.

Fibroblast vs fibrocyte

-
  Fibroblast  is permanent  connective tissue cell responsible for the production of the extracellular matrix (ECM) and collagen fibers which  are essential for tissue structure and repair and play a major role in wound healing. unique features of Fibroblasts : Shape and Structure :  Spindle-shaped (elongated). it contain l arge nucleus that is oval or elliptical . and c ytoplasm is abundant and basophilic (stains blue), reflecting active protein synthesis. and it has  prominent nucleolus , indicating high activity in protein synthesis. Function : it produces the structural components of the extracellular matrix like collagen , elastin , glycosaminoglycans , and proteoglycans .  In response to injury, fibroblasts proliferate and migrate to the site of injury, secreting growth factors and ECM components to promote tissue repair and fibrosis. Major producer of collagen fibers which provide tensile strength to tissues. Elastin Production : ...
