Multiple Choice
Which of the following is the largest part of the forebrain, and what is its primary function?
A
Hypothalamus; regulates homeostasis and endocrine functions
B
Cerebellum; coordinates balance and fine motor control
C
Thalamus; acts as a relay station for sensory information
D
Cerebrum; responsible for higher brain functions such as thought, memory, and voluntary movement
Verified step by step guidance
1
Step 1: Begin by identifying the forebrain's major components. The forebrain consists of the cerebrum, thalamus, hypothalamus, and other structures. Each has distinct functions.
Step 2: Understand the cerebrum's role. The cerebrum is the largest part of the forebrain and is responsible for higher brain functions such as thought, memory, voluntary movement, and sensory processing.
Step 3: Compare the cerebrum to the other options provided. The hypothalamus regulates homeostasis and endocrine functions, the cerebellum coordinates balance and fine motor control, and the thalamus acts as a relay station for sensory information. None of these are the largest part of the forebrain or responsible for higher brain functions.
Step 4: Confirm that the cerebrum is the correct answer based on its size and primary functions, which include cognition, memory, and voluntary motor control.
Step 5: Conclude that the cerebrum is the largest part of the forebrain and is responsible for higher brain functions such as thought, memory, and voluntary movement, as stated in the problem.
