Functions of Protein in cell membrane


  1. Integral proteins provide the structural integrity of the cell membrane.
  2. Channel proteins help in the diffusion of water soluble substances like glucose and electrolytes.
  3. Carrier or  transport proteins help in the transport of substances across the cell mambrane with the help of active and passive transport.
  4. Some carrier proteins act as a pump, by which ions are transported actively across the cell membrane.
  5. Receptor proteins serve  as the receptor sites for hormones and neurotransmitters.
  6. Some protein molecules forms the enzymes and control chemical (metabolic) reactions within the cell membrane.
  7. Some proteins act as a antigens and induce the the process of antibody formation.
  8. Cell adhesion molecules or the integral proteins are responsible for the attachment of cells to their neighbors or to basal lamina.

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

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
