1) What are the different neural progenitor fates that are specified along the dorsal-ventral axis of the neural tube? Why is it important - what are the different neural fates that have to be made?
2) How are different neural fates specified in the ventral half of the neural tube?
1) Neural plate rolls up from the Neural tube.

1) The Shh (sonic hedgehog) signaling molecule is important for patterning the dorsal-ventral axis of the spinal cord. Briefly describe where Shh is expressed and how its expression patterns the spinal cord. 2)What is the role of the proliferating chondrocytes and hypertophic chondrocytes in bone development and bone growth? a) Proliferating chondrocytes: b) Hypertrophic chondrocytes:
1. How do Cerberus, Noggin, Chordin, BMPs and Wnt establish cell fate along the Dorsal-ventral and anterior-posterior axis?
Developmental Biology Discuss how the dorsal-ventral axis is established in amphibian or fish embryos. You should include in your answer the names of the most important molecules. Feel free to discuss manipulations such as knockouts that have provided evidence.
5. (4) What will happen to dorsal/ventral patterning in Xenopus under the conditions listed below (a-h)? From the choices (1-3), select the single most plausible outcome for each experiment 1. No dorsal structures form. 2. Normal embryo development 3. Extra dorsal structures form a) Fertilization followed by a brief UV treatment and physical rotation of the embryo Fertilization followed by a brief UV treatment, then transplant of a ventral vegetal blastomere from a 32-celled embryo onto the dorsal vegetal side...

. What does alcian blue stain? 2. What does alzerin red stain? How do you predict LiCl treatment of zebrafish embryos will affect anterior-posterior axis formation? Will the fish have diminished anterior structures and expanded posterior structures or will the fish have expanded anterior structures and diminished posterior structures? 6. In LiCl treated fish, what parts of the skeleton (bone or cartilage) do you predict will be absent? 7. How do you predict cyclopamine treatment of zebrafish embryos will affect...
please help! I also took a closer picture of the images.. thank you! (1) Explain why neural crest cells migrating in the path2 migrate into the anterior but not posterior somite. Use terms: ephrin, Eph. (Ept) (2) In the intact condition of mouse, the Notch signaling keeps the neural precursors in an immature c proliferation state to expand the number of neuronal cells in later. Explain what will happen if the constitutive active form of Notch (continuously active Notch) is...
For the Speech Neural Network, please describe the possible impairments associated with disruptions to each cortical region below. In your description, you should include what processes that will be degraded/damaged (including upstream processes) and what processes will continue to function. This is especially important in terms of the dorsal, ventral stream for speech perception/production. (Hint #1: do not just consider where the damage is located in terms of cortical region -- also consider whether the damage is bilateral or unilateral....
Plz write in your own text and don't copy answers that was answered before since my teacher has (Plagiarism checker) thank you WRITE IN TEXT NOT IN PIC 1. Where are the choroid plexuses found, and what is their function? 2. Describe the folding of the cerebrum in a sheep brain compared to a human brain. Why are the folds important? 3. The cerebellum of the human is divided into two portions, while the sheep only has one portion of...
1. A line of charge aligned along the z-axis with a length of L has a charge density of de(z) = pz Where is the displacement along the axis and 2 = 0 at the center of the line. B gives the linear charge density per length, determining the charge density at a given location of the line. 2=0 - - a. Discuss the meaning of the linear charge density equation and what it physically means about the amount of...
