Epilepsy is considered a diagnosis when there are how many unprovoked seizures?

Correct Answer: A

Rationale: Epilepsy is diagnosed when an individual experiences at least two unprovoked seizures separated by more than 24 hours. This criterion helps distinguish epilepsy from isolated seizure events caused by temporary factors like fever or alcohol withdrawal.

Correct Answer: B

Rationale: The epididymis is the correct answer because it is the coiled tube where sperm mature and gain motility after being produced in the testes. This maturation process is essential for sperm to become capable of fertilizing an egg. The epididymis also stores sperm until they are ejaculated during sexual activity.

Correct Answer: B

Rationale: Synapse is the correct answer because it is the junction between two neurons where electrical or chemical signals are transmitted. Neurotransmitters are the chemicals that facilitate this transmission, but the gap itself is called the synapse.

Correct Answer: D

Rationale: Positive Rinner & Weber test is the correct answer because these tests are used to assess hearing and are not related to cerebellar function. The cerebellum is involved in coordination and balance, so tests like Romberg's, finger-to-nose, and heel-to-knee are used to evaluate cerebellar integrity, while Rinner and Weber tests are auditory assessments.

Correct Answer: D

Rationale: Brown-Sequard syndrome is the correct answer because it is characterized by ipsilateral motor paralysis and loss of proprioception, and contralateral loss of pain and temperature sensation. This syndrome results from damage to one side of the spinal cord, typically due to trauma or tumors.
