The document discusses the skeleton of fish. It has three main components: the vertebral column, skull, and appendicular skeleton. The skeleton is divided into two parts: the axial firm skeleton and appendicular firm skeleton. The axial skeleton includes the skull, vertebral column, ribs, and intermuscular bones. The skull has two parts - the neurocranium and branchiocranium. The appendicular skeleton comprises the pectoral and pelvic fin supports. The skeleton provides structure, movement, protection, produces blood cells, and acts as storage in fish.

1. WELCOME TO OUR PRESENTATION
Our presentation Topic On SKELETON OF FISH

2. CONTENTS
 Functions of Skeleton
 Main Components
 Distinct Parts of Skeleton

3. INTRODUCTION
 Skeleton is a framework that provides protection and structure
in many types of animal, particularly those of the phylum
chordata.
 The skeleton system serves many important function.
 It provide shape and form for our bodies in addition to
supporting etc.

4. SKELETON OF FISH

5. FUNCTIONS OF SKELETON
There are five function of skeleton:
 Structure
 Movement
 Protection
 Blood Cell Produce
 Storages

6. MAIN COMPONENTS
The skeletal system of fishes have three components:
 The vertebral column
 The skull
 The appendicular skeleton

7. DIVISIONS OF THE SKELETON
The skeleton is divided into two distinct parts:
 Axial Firm Skeleton
 Appendicular Firm Skeleton

8. AXIAL FIRM SKELETON
 The Skull
 The Vertebral Column
 The Ribs
 The Intermuscular Bones

9. SKULL
Two distinctive parts:
 Neurocranium
 A series of inner elements that provide the floor to the brain case and
protect the olfactory
 A series of outer dermal bones that roof the brain case,and give form
to the face
 Branchiocranium
 Jaws or mandibular
 Hyal
 The gill arches

10. SKULL

11. VERTEBRAL COLUMN
 A series of segments
 One vertebra per body segment
 Modified according to the body region
 Bear ribs

12. RIBS
 A series of arches
 That protect the spinal cord

13. INTERMUSCULAR BONES
 Small,splint bones of various shapes in the myosepta
 “C” “I” “Y” shaped
 Groups represented include herrings,pikes,suckers,carps,some
salmons

14. APPENDICULAR FIRM SKELETON
 Pectoral fin supports
 Pelvic fin supports

15. CONCLUSION
 By the study of fish skeleton,we can know about the fish body
structure
 It gives us a lot of information about fish body and their functions
