Compare the dermatocranium,splanchnocranium,chondocranium,appendicular skeleton and axial skeleton of the ff:
1. fish
2. amphibian
3. reptile
4. bird
5. mammal
i know somebody younger than this post..... thats spooky- SCARY SKELETONS, AND SHIVERS DOWN YOUR SPINE
I suggest that you answer this by first setting up a table with dermatocranium, splanchnocranium, chondocranium, appendicular skeleton and axial skeleton across the top and fish, amphibian, reptile, bird, and mammal down the side. This is so that you have a way of comparing the information as you collect it.
You might want to start with definitions of the parts of the cranium from one of the on-line dictionaries.
Thanks for the tip!
To compare the dermatocranium, splanchnocranium, chondocranium, appendicular skeleton, and axial skeleton of different animals, such as fish, amphibians, reptiles, birds, and mammals, we need to understand the different components of each skeletal system.
1. Fish:
- Dermatocranium: The dermatocranium of a fish is composed of dermal bones that cover the skull. These bones provide protection to the brain and sense organs.
- Splanchnocranium: The splanchnocranium in fish mainly consists of cartilaginous structures that support the gills and jaws.
- Chondocranium: The chondocranium in fish refers to the cartilaginous parts of the skull that enclose and protect the brain.
- Appendicular Skeleton: The appendicular skeleton in fish includes the fins and their supporting elements, such as the pectoral and pelvic girdles.
- Axial Skeleton: The axial skeleton in fish consists of the skull, vertebral column, and ribs. It provides support and protection for the internal organs.
2. Amphibians:
- Dermatocranium: The dermatocranium in amphibians is composed of a combination of dermal bones and cartilaginous structures that cover the skull.
- Splanchnocranium: The splanchnocranium in amphibians primarily consists of cartilage and is responsible for supporting the jaws and hyoid apparatus.
- Chondocranium: Similar to fish, the chondocranium in amphibians refers to the cartilaginous parts of the skull that protect the brain.
- Appendicular Skeleton: The appendicular skeleton in amphibians consists of the forelimbs and hindlimbs, along with their associated girdles.
- Axial Skeleton: The axial skeleton in amphibians includes the skull, vertebral column, and ribs, providing support and protection to the internal organs.
3. Reptiles:
- Dermatocranium: The dermatocranium in reptiles is composed of dermal bones that form the outer layer of the skull.
- Splanchnocranium: The splanchnocranium in reptiles supports the jaws and hyoid apparatus and is primarily made up of cartilaginous structures.
- Chondocranium: The chondocranium in reptiles refers to the cartilaginous and bony components that enclose and protect the brain.
- Appendicular Skeleton: The appendicular skeleton in reptiles consists of the limbs and their associated girdles, facilitating movements such as walking or crawling.
- Axial Skeleton: The axial skeleton in reptiles includes the skull, vertebral column, and ribs, providing support and protection to the internal organs.
4. Birds:
- Dermatocranium: The dermatocranium in birds is composed of fused dermal bones that form a rigid beak and a protective skull.
- Splanchnocranium: The splanchnocranium in birds supports the jaws and is primarily cartilaginous, forming the bony beak.
- Chondocranium: The chondocranium in birds contains cartilaginous and bony components that protect the brain.
- Appendicular Skeleton: The appendicular skeleton in birds includes the wings, along with their associated girdles, which are modified for flight.
- Axial Skeleton: The axial skeleton in birds consists of the fused skull, vertebral column, and ribs, providing support and protection to the internal organs.
5. Mammals:
- Dermatocranium: The dermatocranium in mammals is composed of fused dermal bones that form the skull's protective outer layer.
- Splanchnocranium: The splanchnocranium in mammals contains cartilaginous and bony structures that support the jaws and middle ear bones.
- Chondocranium: The chondocranium in mammals refers to the cartilaginous and bony parts of the skull that enclose and protect the brain.
- Appendicular Skeleton: The appendicular skeleton in mammals includes the forelimbs and hindlimbs, along with their associated girdles, facilitating various types of locomotion.
- Axial Skeleton: The axial skeleton in mammals consists of the skull, vertebral column, ribs, and sternum, providing support and protection to the internal organs.
Please note that the specific composition and structure of these skeletal components may vary across different species within each animal group.
