1.
Which of the following forms the brain?
Correct Answer(s)
A. Occipital Lobe
B. Temporal Lobe
D. Parietal Lobe
Explanation
The brain is formed by the Occipital Lobe, Temporal Lobe, and Parietal Lobe. The Occipital Lobe is responsible for processing visual information, while the Temporal Lobe is involved in auditory perception, memory, and language comprehension. The Parietal Lobe plays a role in sensory perception, spatial awareness, and attention. These three lobes are essential components of the brain and contribute to its overall functioning.
2.
Which part of the brain is concerned with emotions?
Correct Answer
D. Amygdala
Explanation
The amygdala is a small, almond-shaped structure located deep within the brain. It is primarily responsible for processing and regulating emotions, particularly fear and aggression. It plays a crucial role in the formation of emotional memories and the interpretation of emotional facial expressions. Damage or dysfunction in the amygdala can result in difficulties in recognizing and responding to emotions. Therefore, the amygdala is the correct answer as it is directly associated with the regulation of emotions in the brain.
3.
The spinal cord has _____ layer(s) of protective covering(s) called meninges.
Correct Answer
A. 3
Explanation
The spinal cord is protected by three layers of meninges. These layers, known as the dura mater, arachnoid mater, and pia mater, provide a protective covering for the delicate spinal cord. The dura mater is the outermost layer, followed by the arachnoid mater, and finally the pia mater, which is the innermost layer. These layers help to cushion and protect the spinal cord from injury or damage.
4.
What is the seat of intelligence, judgment and problem solving?
Correct Answer
A. Frontal lobe
Explanation
The frontal lobe is responsible for various cognitive functions, including intelligence, judgment, and problem-solving. It plays a crucial role in decision-making, reasoning, and planning. This area of the brain is involved in complex thinking processes and is often considered the seat of higher-order cognitive abilities.
5.
Which function is lost with the cerebellum not working?
Correct Answer
D. None of the above
Explanation
The cerebellum is responsible for coordinating movement, balance, and posture, but it is not directly involved in emotions, reasoning and judgment, or the sleep-wake cycle. Therefore, none of the above functions are lost when the cerebellum is not working.
6.
A human being has these many pairs of cranial nerves (type in number and not in words) __________
Correct Answer
31
Explanation
A human being has 31 pairs of cranial nerves. These nerves emerge from the brain and control various functions of the head, neck, and some parts of the body. Each pair of cranial nerves has a specific function, such as controlling eye movement, facial expressions, hearing, taste, and sensation in different areas. The correct answer states the number of cranial nerves in numerical form, which is 31.
