SPECIALIZED TISSUE Flashcards
WHAT IS THE FUNCTION OF SKELETAL TISSUE?
FORMS THE ENDOSKELETON OF VERTEBRATES.
WHAT IS THE NAME OF CELLS OF CARTILAGE?
CONDROCYTE
WHAT IS THE NATURE OF MATRIX OF CARTILAGE?
RIGID, PLIABLE AND RESIST COMPRESSION.
DEVELOPMENT OF CARTILAGE IS UNIDIRECTIONAL.
TRUE OR FALSE
TRUE. THE DEVELOPMENT OF CARTILAGE IS UNIDIRECTIONAL.
WHY IS THE DEVELOPMENT OF CARTILAGE UNIDIRECTIONAL?
DUE TO THE PRESENCE OF SINGLE CONDROBLAST LAYER.
HOW MANY CHONDROBLAST ARE PRESENT IN EACH LACUNAE?
1-4 CHONDROBLAST.
ALL CARTILAGE ARE AVASCULAR?
FALSE, IN THE EMBRYONIC STAGE VASCULAR TISSUE IS PRESENT IN THE CARTILAGE.
WHICH IS THE MOST COMMON TYPE OF CARTILAGE?
HYALINE
WHAT IS THE LOCATION OF HYALINE CARTILAGE?
- TRACHEAL RINGS
- LARYNX
- AT THE TOP OF LONG BONES (EPIPHYSIS)
- COASTAL PARTS OF RIBS
- NASAL SEPTUM
what is the nature of matrix of hyaline cartilage?
semi transparent
what is the location of elastic cartilage?
- external ear joint (ear pinna)
- at tip of nose
- epiglottis
only elastic cartilage is present in larynx.
true or false
false
it is found in both hyaline and elastic cartilage.
which is the strongest cartilage?
white fibrous cartilage
in which cartilage the perichondrium covering is absent?
white fibrous cartilage.
Which cartilage cannot be repaired if damaged?
White fibrous cartilage
What is the location of white fibrous cartilage?
- In between inter vertebral disc
- In pubic symphysis
What is the nature of matrix of calcified cartilage?
In the matrix little amount of calcium salt appears.
What is the location of calcified cartilage?
- Suprascapula (part of pectoral girdle)
- Pubis of frog (part of pelvic girdle)
Which is the hardest tissue of the body?
Bone due to the presence of inorganic matter in large amount, around 70%.
What type of tissue is bone? (Vascular / avascular)
Vascular
Bone shows unidirectional movement. True or false
False, the development of bone is bidirectional due to the presence of double osteoblast layer.
What are the types of bone marrow?
Red and yellow bone marrow.
What is the function of RED BONE MARROW?
main site for erthropoiesis (manufacture of RBCs) after maturation.
What is the function of yellow bone marrow?
Stores little fats and also forms few WBCs.
What happens to the bone marrow in case of severe anemia?
In the case of severe anemia, yellow bone marrow changes into red bone marrow.
What are the 2 main salts present in bone?
The 2 main salts that are present in bones are:
a. Calcium phosphate
b. Calcium carbonate
What is the composition of bone?
The bone contains 70% inorganic matter and 30% organic matter (protein).
Both composition of bone is?
Calcium phosphate.
Haversion canal are found in all bones, true or false?
False, haversian canals are only found in long mammilian bone.
What are included in haversian system?
Haversian canal, volkmann canal, lamellae, canali culi.
LA CUNAE IS NOT INCLUDED IN HAVERSIAN SYSTEM.
What is the function of haversian system?
It is meant for providing nutrition to bone cells.
What happens when a frog’s bone is kept in HCL solution?
When any bone is kept in HCL solution, then it decalcifies.
What happens when a rabbit bone is kept in KOH solution?
When any bone is kept in KOH solution, then no change will happen. It will only appear clean.
