HISTOLOGY Flashcards
1
Q
- CONNECTIVE TISSUES ?
A
- the connective tissues are a group of tissues which connects or binds other tissues in the body .
2
Q
- components of the connective tissue ?
A
- cells .
- matrix ,
- ground substance ,
- fibers .
3
Q
- types of ( CT ) fibers ?
A
- collagen fibers - white fibers .
- elastic fibers - yellow fibers .
- reticular fibers .
4
Q
- collagen ( CT ) fibers ?
A
- are white , long , straight and unbranched ,
- its made up of a collagen protein ,
- they are in bundles .
5
Q
- elastic ( CT ) fiber ?
A
- its wavy and it found in bundles ,
- its made up of elastin protein .
6
Q
- reticular ( CT ) fiber ?
A
- its less thickness then white fiber ,
- it needs silver nitrate most of the time .
7
Q
- types of ( CT ) cells , according to motion and according to shape ?
A
- according to motion :
- migrant ,
- nonimmigrant .
- according to shape :
- branched ,
- unbranched .
8
Q
- nonimmigrant motion ( CT ) cells ?
A
- fibroblast and fibrocytes ,
- chondrocytes ,
- osteocytes ,
- mesenchyme cells
- mast cells
- macrophage ,
- fat cells .
9
Q
- migrant motion ( CT ) cells ?
A
- lymphocytes ,
- plasma cells ,
- neutrophils ,
- acidophils ,
- basophils ,
- macrophage ,
- monocytes .
10
Q
- branched shape of ( CT ) cells ?
A
- fibroblast and fibrocytes .
- chondrocytes ,
- osteocytes ,
- macrophage ,
- mesenchyme cells .
11
Q
- unbranched shape of ( CT ) cells ?
A
- lymphocytes ,
- plasma cells ,
- neutrophils ,
- acidophils ,
- basophils ,
- mast cells ,
- fat cells ,
- monocytes .
12
Q
- fibroblast and fibrocytes ( CT ) ?
A
- its the most common
- they are responsible of fibers secretion and the
secretion of the complex carb in the matrix ( intercellular substance ) . - long , branched , stretchy , pointed , it have two oval nucleus in the cytoplasm .
13
Q
- chondrocytes ( CT ) ?
A
- its the responsible of Cartilage creation ,
- its responsible of intercellular substance secretion .
14
Q
- osteocytes ( CT ) ?
A
- its the responsible of bond tissue creation and the matrix secretion , can be find in preservatives .
15
Q
- mesenchyme cells ( CT ) ?
A
- its origin is from mesoderm , it is undifferentiated cells ,
- it can differentiate to all types of tissue cells ,
- have a Long appendages astral shape ,
- have a big nucleus in the cytoplasm ,
- are located in the umbilical cord .
16
Q
- mast cells ( CT ) ?
A
- contains many granules rich in heparin ( anticoagulant ) , histamine ( vasodilator ) , seratonin ( vasocontrictor ) .
ماست سيل ، الخلايا الصارية ، الخلاية الصادية : هي خلايا كبيرة بيضاوية الشكل ذات نواة مركزية مستديرة والسيتوبلازم به حبيبات كبيرة داكنة اللحون ( حويصلات ) مملؤة بالهستامين و الهيبارين وسيراتونين تفرز المواد ضد ضد المواد الغريبة وقد تسبب تقاعلات الحسااسية .
17
Q
- adipose cells / fat cells ( CT ) ?
A
الخلاية الذهنية او الخلاية الشحمية : تكتر بها المواد الدهنية وهي تبدأ بقطرات صغيرة دهنية تتحد مع بعضها في كرة دهنية كبيره وبذلك ينحصر السيتوبلازم في طبقة رقيقة محيطة تبطن غشاء الخلية وتدفع النواة الي احد جوانب الخلية ، ويوجد بها نوعين وحيدة الحبيبة الدهنية ومتعددة الحبيبة الدهنية .
