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.
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.
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
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
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
