Question

Which condition is associated with no nervous sensation?

1) Huntington disease
2) Anesthesia
3) Anencephaly
4) Analgesia
5) Alzheimer disease

Answer 1

2) Anesthesia

The condition associated with no nervous sensation is anesthesia, which temporarily blocks or reduces sensations, not to be confused with neurodegenerative diseases or disorders like congenital analgesia that have different symptoms and causes.

Step-by-step explanation:

The condition associated with no nervous sensation is anesthesia. Anesthesia refers to a temporary induced state where sensation, particularly pain, is blocked or greatly reduced. This is different from conditions like Huntington disease, anencephaly, analgesia, and Alzheimer disease, which are neurodegenerative diseases or specific types of nervous system disorders with varied symptoms and causes. For instance, congenital analgesia, also known as congenital insensitivity to pain, is a rare genetic disorder that results in the inability to experience pain, but it is not induced like anesthesia and is not the absence of all sensation but specifically of pain.
