difference between anatomy

Difference between indirect and direct hernia indirect hernia direct hernia abdominal contents enter the inguinal canal through deep inguinal ring abdominal content enter through inguinal triangle of Hasselbach it is a congenital lesion it is an acquired lesion it is situated lateral to inferior epigastric artery it is situated medial to inferior epigastric artery it is usually occur in young adult it is usually occur in old individual it is usually unilateral it is usually bilateral it is associated with processus vaginalis it is not associated with processus vaginalis it is common in female more seen in male , rare in female it is common in children it is rarely occur in children

The lateral part of rectus abdominis muscle produce a groove in the anterior abdominal wall , is known as linea semilunaris. This groove is important because medial to this  groove and lateral to this  groove the layers of anterior abdomnal wall is different Layers of anterior abdominal wall, medial to the linea semilunaris  (from before backward ) 1)     Skin 2)     Superficial fascia : fascia camper and fascia scarpa 3)     Aponeurosis of external oblique abdominis 4)     Aponeurosis of anterior layer of internal oblique abdominis 5)     Rectus abdominis muscle 6)     Aponeurosis of posterior layer of internal oblique abdominis 7)     Aponeurosis of transversus abdominis 8)     Fascia transversalis 9)     Extraperitoneal tissue 10)              ...

ant part of rectus sheath rectus abdominis Pos part of rectus sheath Above costal margin : 1 aponeurosis  (EOA) no rectus sheath Costal margin to arcuate line : 2 aponeurosis (EOA & IOA) 2 aponeurosis (IOA & TA) Below the arcuate line : 3 aponeurosis (EOA, IOA, TA) no rectus sheath

Difference between collagen,  reticular and elastic fibre Features Collagen fibre Reticular fibre Elastin fibre Appearance Colourless hence called white collagen fibre Only demonstrated by special silver techniques hence called argyrophilic fibres . by taking up silver salt . it become back Yellow Distribution Widely distributed  particularly in tendons, joint capsules  and ligaments Lymphatic system,  basement membrane Blood vessels , lungs elastic ligament of vocal cord Structure They run in bundles in straight or sinus course  a bundle of the fibres branched but an individual fiber do not branch fibrils present The individual fibers branch and form a network of fiber . fibrils present The individual fibers branch and form a network of fibre. No fibrils Consisten...

Topics Microfilament Intermediate filaments Microtubules Features Thin, flexible filaments Strong, stable structures Exhibit dynamic instability Shape Double stranded linear helical array Ropelike fibers Non-branching long hollow cylinders Protein G-actin Different types of proteins Dimmers of α tubulin and β tubulin Enzymatic activity ATP hydrolytic activity None GTP hydrolytic activity Polarity Yes, both end grow  No Yes one growing end and other non-growing  end  Source of energy required for assembly ATP N/A GTP Location in cell Terminal web, core of microvilli, concentrated beneath the plasma membrane , contractile elements of muscles Extend across cytoplasm connecting desmosomes and hem...

Difference between organelle and inclusions Organelle Inclusions it is a structure within the cytoplasm that has a specific function . they are stored nutrients secretory product and pigment granules Ex: lipid droplets in fat cells, pigment granules in certain cells of skin and hair, glycogen granules in the liver and muscle cells membranous organelle are separately enclosed within their own lipid bilayers some of inclusion such as pigment granules are surrounded by a plasma membrane but lipid droplets and glycogens are not surrounded by a plasma membrane they are living they are lifeless it is more organized at eukaryotic cell it is found in both eukaryotic and prokaryotic cell it is metabolically active it is metabolically inactive they are permanent structure of cell they are temporary or permanent  structure of cell they are cytoplasmic structu...
