Skeletal System Endoskeleton and Cartilage

Skeletal System- Endoskeleton consist of bone and Cartilage का बना बना होता है । आज इस Article के माध्यम से मानव शरीर मे कितना bone होता है और किस Part मे कितना -कितना  Bone होता है ।

इसके बारे मे विस्तृत से जानेगे । जिसके बाद आप को मानव शरीर मे कितना Bone होता आप ये अच्छे से जान पाएगे । साथ मे किस Part मे कितना Bone होता है । और उसका Short मे क्या कार्य या Support है ।

Skeleton System Function of human being 

1. Skeleton System provide surface for muscles attachment.
2. It form Structural framework of the Body.
3. It is Stored minerals and fats.
4. Provide site for blood cell formation.
5. Protect visceral organ Like -Lung
6. Help in breathing and sound conduction.

How many bone in human being

Human being embryonic Endoskeleton 270 bone but in adult only 206 bone visual. Endoskeleton are divided into two part

मानव शरीर मे जब बच्चा (गर्व) मे होता है उस समय 270 total Bone होता है । लेकिन जब वो जन्म ले लेता है और उसके बाद जब वो adult age मे आता है total bone 206 हो जाता है ।

तो इस प्रकार कोई कहे मानव शरीर मे कितना Bone होता है तो आप दोनों तरह से अच्छे से बता पाएगे । पूरे शरीर के bone को दो भाग मे बटा गया है । तो आइये जानते है ।

How many part of bone in human being of skeletal system

मानव शरीर मे Bone को दो भागो मे बाटा गया है तो आइये देखते है ।

1. Axial skeleton- इस part मे total 80 bone होती है जो कुछ इस प्रकार है नीचे देखे । 

• Skull -22 Bone – इसमे भी दो भाग होता है

1. Cranium bone – 8
2. Face -14

• Hyoid bone – 1
• Sternum bone -1
• Ribs 12 pair (12+12)
• Vertebral column- 26 या 33
• Ear ossicles 3 pair (3+3)

1. 2.Appendicular skeleton इस part मे total 126  bone होती है जो कुछ इस प्रकार है नीचे देखे ।

• Girdle

1. Pectoral Girdle 2 pair (2+2) जिसका नाम  clavicles and  scapula होता है । दोनों तरफ 2- 2 होता है ।
2. Pelvic Girdle 2  (1+1) होता है 1-1 दोनों तरफ होता है ।

• Limb Bone or forelimb 30 x 2 =60 Bone इसके अंतर्गत इस प्रकार की bone होती है नीचे देखे

1. Humerus bone – 1
2. Radius bone -1
3. Ulna bone -1
4. Carpus bone -8
5. Metacarpus bone – 5
6. Phalanges bone – 14

ये Upper Limb मे होता है और ये दोनों तरफ मिलाकर 60 total bone होता है (30+30)

• Hind Limb or Lower Limb 30 x 2 =60 Bone इसके अंतर्गत इस प्रकार की bone होती है नीचे देखे

1. Femur bone – 1
2. Patella bone – 1
3. Tibia bone – 1
4. Fibula bone -1
5. Tarsals bone – 7
6. Metatarsals bone – 5
7. Phalanges bone -14

ये Lower or Hind Limb मे होता है और ये दोनों तरफ मिलाकर 60 total bone होता है (30+30)
