Golgi apparatus

-
Name :- Golgi apparatus, Golgi body, Golgi complex, Post office of the cell, Shipping department of the cell (Camillo Golgi (1898) first discovered, hence the name is Golgi).

Properties :
  • It is an membrane bound organelle situated near the nucleus.
  • It is present in all cells except RBCs.
  • Usually, each cell has one Golgi apparatus.
  • Each Golgi apparatus consists of 5-8 flattened membranous sacs called cisternae (0.5-1.0 micrometer).
  • Golgi apparatus has two ends or faces, namely cis face (situated near the endoplasmic reticulum) and trans face (situated near the cell membrane).
Functions :
Major functions of Golgi apparatus are processing, packing, labeling and delivery of proteins and lipids to different part of the cell or outside of the cell.
  1. Processing :- glycoproteins and lipids are modified here.
  2. Packaging :- modified materials are packed in the form of secretory granules, secretory vesicles and lysosomes.
  3. Labeling and delivery :- Golgi apparatus sort out the processed materials and labels them (such as phosphate group) then distribute in or out side of the cell according to demand.

Clavicle  Synonames Collar bone, Beauty bone. Anatomical position It extends laterally and horizontally at the root of the neck Side Determination  1. Flattend end laterally. 2. Medial two-third of clavicle is convex anteriorly. 3. Rough area on the lateral side faces inferiorly. Special Features  It is only long bone which lies horizontally. It has no medullary cavity (Bone marrow). It is the first bone to ossifies in the body ( second bone to ossifies Mandible). Almost whole clavicle visible through skin can be palpable. It has the only long bone which has two primary center of ossification. It has only long bone which ossifies in membrane. General features of right clavicle (a) Superior aspect (b) Inferior aspect Features It has 2 ends (Medial or Sternal, Lateral or Acromial end) and a shaft. Lateral end  It is flattend from above downwards. It articulate with the acromian process of scapula to form acromioclavicular join

Lysosomes

-
Image
Name :- Lysosomes, garbage system of the cell, suicidal bag of the cell Properties : These are membrane bound vesicular structures founds throughout the cytoplasm. These are formed by the process of packaging in the golgi apparatus. Enzymes of lysosomes are synthesized in rough endoplasmic reticulum. Among the organelles, the lysosomes have the thickest covering membrane that is formed by a bilayered lipid material . Lysosomes have 50 different hydrolytic enzymes, known as acid hydroxylases. Types of Lysosomes : Primary lysosomes, this is an inactive of form of lysosomes. Secondary lysosomes, this is an active form of lysosomes (lysosomes active during phagosome or endosome and at this time lysosomes pH become acidic and enzymes are activate). Lysosomal Enzymes :   Proteases :- which hydrolyze the proteins into amino acids. Lipases :- which hydrolyze the lipids into fatty acids and glycerides. Amylases :- which hydrolyze the polysaccharides into glucose. Nucleases :- whi

Femur The femur is a latin word it means thigh. Femur is the longest and strongest bone of the body. Femur has 27% length of total body length. Weight of femur is about 380gm in males and 279gm in females. Quantity of femur are two in number. Side Determination 1. Head directed medially. 2. Medial and lateral condyle (lower end) inferiorly. 3. Cylindrical shaft is convex forward. Joint Formation  1. Hip joint - between head of femur and acetabulum of Hip bone . 2. Knee joint - between lower end of femur and upper end of Tibia. Features  It has upper end, lower end and shaft. Right femur anterior aspect Upper end It has head, neck, greater trochanter ( Greek- runner), lesser trochanter, intertrochantric line and intertrochantric crest. Head -  It forms more than half a sphere and is directed madially, upwards and slightly forwards. It articulates with the acetabulum to form hip joint. It has a pit that is called fovea.

Pneumonia

Pneumonias  Definition :  It is an acute inflammation of lungs parenchyma with consolidation distal to terminal bronchioles ( consisting of the respiratory bronchiole, alveolar ducts, alveolar sacs and alveoli ).It may be infective and non-infective. Pathogenesis :  Microorganism can enter into the lungs by following route after  failure of defensive mechanism  - i. Inhalation of air microbes. ii. Aspiration of the microbes from the nasopharynx or oropharynx. iii. Haematogenous spread from a distant focus of infection such as - vector population, environmental characteristics. iv. Direct spread from a adjoining site of infection. Classification : 1. On the basis of anatomical regions - Lobar Pneumonia Bronchopneumonia or Lobular Pneumonia Interstitial Pneumonia Features of lobar and lobular pneumonia 2. On the basis of clinical aspects - Community-acquire Pneumonia Health care-associated Pneumonia (Hospital acquired Pneumonia) Ventilator-associated Pneu
