Some cells of the central nervous system are located in the
- a. spinal cord.
- b. muscles
- c. glands.
- d. Both a and c are correct.

Introduction:
Nervous system controls and coordinates the functions of body. It communicates through the network of cells and the nerve impulses sent by the neuron cells. The nervous system in the vertebrates is divided into two main divisions, central nervous system and peripheral nervous system.
Answer to Problem 1MCQ
Correct answer:
Some cells that belong to central nervous system are located in the spinal cord. Therefore, option (a) is correct.
Explanation of Solution
Reason for the correct statement:
The central nervous system consists of spinal cord and brain. The cells of central nervous system would belong to these organs only. The main function of these organs is to combine the sensory information and coordinate the responses of the body.
Option (a) is given as “spinal cord”.
As, “some cells of the central nervous system are located in the spinal cord”, is the right answer.
Hence, option (a) is correct.
Reasons for the incorrect statements:
Option (b) is given as “muscles”.
Muscles are the part of the peripheral nervous system. Hence, it is a wrong answer.
Option (c) is given as “glands”.
Glands receive nerve impulses from the central nervous system carried by the peripheral nervous system. Hence, it is a wrong answer.
Option (d) is given as “Both a and c are correct”.
Spinal cord is the part of central nervous system whereas glands are the part of peripheral nervous system. Hence, it is a wrong answer.
Hence, options (b), (c) and (d) are incorrect.
Spinal cord is the part of the central nervous system. Thus some cells of this nervous system are located in the spinal cord.

- Using quail and chicken embryos, what kind of experiment would you conduct to test if rib forming somites have their axial identity specified before segmentation? How do we know this phenotype is due to axial identity being specified before segmentation and not due to our experimental method?arrow_forward8. Aerobic respiration of a 5 mM solution of tripeptide that is composed of the following three amino acids; alanine, leucine and isoleucine. Alanine breaks down to pyruvate, leucine breaks down to Acetyl-CoA and isoleucine breaks down to succinyl-CoA. Alanine NADH FADH2 OP ATP SLP ATP Total ATP Leucine Isoleucine Totals Show your work using dimensional analysis here: 4arrow_forward9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. fatty acids glycerol 18 carbons 12 carbons 0=arrow_forward
- If using animals in medical experiments could save human lives, is it ethical to do so? In your answer, apply at least one ethical theory in support of your position.arrow_forwardYou aim to test the hypothesis that the Tbx4 and Tbx5 genes inhibit each other's expression during limb development. With access to chicken embryos and viruses capable of overexpressing Tbx4 and Tbx5, describe an experiment to investigate whether these genes suppress each other's expression in the limb buds. What results would you expect if they do repress each other? What results would you expect if they do not repress each other?arrow_forwardYou decide to delete Fgf4 and Fgf8 specifically in the limb bud. Explain why you would not knock out these genes in the entire embryo instead.arrow_forward
- You implant an FGF10-coated bead into the anterior flank of a chicken embryo, directly below the level of the wing bud. What is the phenotype of the resulting ectopic limb? Briefly describe the expected expression domains of 1) Shh, 2) Tbx4, and 3) Tbx5 in the resulting ectopic limb bud.arrow_forwardDesign a grafting experiment to determine if limb mesoderm determines forelimb / hindlimb identity. Include the experiment, a control, and an interpretation in your answer.arrow_forwardThe Snapdragon is a popular garden flower that comes in a variety of colours, including red, yellow, and orange. The genotypes and associated phenotypes for some of these flowers are as follows: aabb: yellow AABB, AABb, AaBb, and AaBB: red AAbb and Aabb: orange aaBB: yellow aaBb: ? Based on this information, what would the phenotype of a Snapdragon with the genotype aaBb be and why?
