Group Dissection

Organisms in order of preference

1. Chicken: I want to dissect a chicken because a lot of animal research has been done on chickens and it would be interesting to see the layers of skin covered underneath the feathers. Also, I eat chicken and I would want to see what the bare skin looks like before it is cooked. 2. Rabbit: I want to dissect a rabbit because it is the only mammal in the group covered in fur which means the rabbit has more similarities compared to a human. Thus, it would be easier comparing the human anatomy with that of the rabbit. 3. Pigeon: I want to dissect a pigeon because I'm curious as to what the skin looks like, its texture and how it compares to that of humans.

Feedback responses

vertebral column of pigeon

I need to contribute to my team member's sandbox and add in the section on the vertebral column of the pigeon. Other plans for revision for my section includes adding in references and wikilinks to my section when necessary, Adding images (this could be from Wikimedia or pictures from lab), highlighting the importance of the structure and function of the vertebral column of a pigeon and also comparing and contrasting differences with the information of the Wikipedia bird page.

Comments from Dr. Schutz:

• You were all supposed to enter your responses to review in your common sandbox and not in your separate sandboxes (where you are fine to draft). I have found them and I am leaving individual responses for all of you. However, the individual responses make it hard to see how you are integrating your work.

-If you are working on the vertebral column, how will this integrate with your colleague working on the neck? How will you prevent overlap between you? -What pages will you contribute to? -I'd like to see you really develop your elements in this coming draft. See me with questions.

• As you work through your drafts, be sure to use the rubric I provided

Week 10

Vertebral Column of the neck

I will edit the bird anatomy page and make the vertebral column a section. I will talk about the divisions of the vertebral column and explain each of them.

The vertebral column of a pigeon is divided into four sections just like that of a bird. They are the Cervical, Thoracic, Synsacrum and pygostyle vertebrae. The cervical vertebral contains 14 vertebrae. It supports the neck region of the pigeon as well as support the head of the pigeon. This allows for efficient movement of the neck. The Thoracic vertebral consists of up to five vertebrae. The synsacrum consists of a compact skeletal mass that provides rigidity. the vertebrae that make up the synsacrum includes the posterior thoracic, lumbar, sacral and anterior caudal. The pygostyle is a compressed skeletal structure composed of the fusion of the last four vertebrae.

Week 11

Actually, the vertebral column of a pigeon is divided into five regions. Cervical, Dorsal, Synsacrum, Caudal, and Pygostyle.

Since I do not have pictures of my dissected pigeon's vertebral column, I took a picture of the pigeon model from lab and marked regions of the vertebral column. The Pygostyle from the lab model is missing but this region was annotated with a green ink. In lab next week, I also hope to take lateral pictures of the vertebral column of the pigeon.

This image shows the regions of the vertebral column of a feral pigeon

Week 12

Vertebral column divisions.

• Cervical
• Dorsal: this comprises of the thoracic region of the vertebrae.
• Synsacrum: This region is similar to the sacrum in mammals. This is unique in the pigeon because it is a fusion of the sacral, lumbar and caudal vertebra. It is attached to the pelvis and supports terrestrial locomotion of the pigeon's legs.
• Caudal: This region is similar to the coccyx in mammals and helps control the movement of feathers during flight.
• Pygostyle: This region is made up of 4 - 7 fused vertebrae and is the point of feather attachment.
