zimovet [89]

Answer:

Cerebellum

Explanation:

According to my research on studies conducted by various neurologists, I can say that based on the information provided within the question the doctors will likely find Christy's problem in the Cerebellum which is located in the Hindbrain. The Cerebellum is responsible for coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity. A problem with the Cerebellum can impair movements similar to what Christy is experiencing.

I hope this answered your question. If you have any more questions feel free to ask away at Brainly.

The appearance of a pebbly texture on the surface of a deep wound indicates what process is taking place?
irakobra [83]
In a deep wound, there might be a few layers of tissue that need to be rebuilt because they were lost. In this rebuilding process this pebbly texture can be seen and it indicates that granulation is taking place (that's the process). Granulation is when small blood vessels and capillaries start to develop vertically to the outside part of the wound, being supported by connective tissue, and surrounded by cells of many other types for different purposes, such as immunitary functions or specialised tissue functions. This tissue growing is characteristic of healing and it presents this granulated/pebbly texture to it.
