Nice test.

2. To answer this question, we need to know the layers of the head that the bullet has penetrated on its way to just outside the dura mater. The dura mater is the outermost layer of the brain and is located just beneath the skull. So, if the bullet has stopped just outside the dura mater, it means it has penetrated the skull. The bone is the innermost layer that the bullet has penetrated. Therefore, the correct answer is B. Bone.

3. To answer this question, we need to know which part of the brain is responsible for the maintenance of muscle tone and coordination of muscle movements. The part of the brain that is responsible for this is the cerebellum. Therefore, the correct answer is D. Cerebellum.

4. To answer this question, we need to determine which activity requires the coordination of both hemispheres of the brain. Learning a new language requires the coordination of both hemispheres as it involves processing and production of language, which are functions localized in different parts of the brain. Therefore, the correct answer is A. Learning a new language.

5. To answer this question, we need to know the components of a single neuron. A single neuron possesses several dendrites, which receive signals from other neurons, and one axon, which transmits signals to other neurons. Therefore, the correct answer is B. Several dendrites and one axon.

1. To answer this question, we need to understand what catheterization is. Catheterization refers to the placement of a drainage tube into the bladder. Therefore, the correct answer is D. Placement of a drainage tube into the bladder.

2. To answer this question, we need to identify the condition related to the male sex gland surrounding the urethra just under the urinary bladder. This condition is called benign prostatic hyperplasia. Therefore, the correct answer is C. Benign prostatic hyperplasia.

3. To answer this question, we need to know where spermatozoa are manufactured. Spermatozoa are manufactured in the seminiferous tubules, which are part of the testes. Therefore, the correct answer is B. Seminiferous tubules.

4. To answer this question, we need to determine where urine is formed. Urine is formed by the nephrons, which are functional units of the kidneys. Therefore, the correct answer is A. Nephrons.
