Introduction:
Sensory neurons are the nerve cells in the nervous system that works to convert signals from the external environment to the internal stimuli. They are also termed as afferent neurons, as they transfer the signals from the various parts of the body to the central nervous system.
Answer to Problem 1E
Solution:
The correct answer is option (b) the somatosensory cortex.
Explanation of Solution
Explanation/justification for the correct answer:
Option (b) is the somatosensory cortex. Touch perception is processed by the somatosensory system. This system includes the sensory receptors, peripheral sensory neurons, and brain cells. Hence, this option is correct.
The explanation for the incorrect answer:
Option (a) is the basal nuclei. The basal nuclei are the region at the base of the brain, which includes the clusters of neurons or nerve cells. This portion is responsible for the movement and coordination of the body. Hence, this option is incorrect.
Option (c) is the hypothalamus. The main function of the hypothalamus is to secrete hormones and controlling the
Option (d) is the limbic system. The functions of the limbic system include motivation, emotion, learning, and memory. Hence, this option is incorrect.
Option (e) is the hippocampus. It is an important organ of the limbic system. It is basically associated with long-term memory. Hence, this option is incorrect.
Touch perception requires that sensory neurons from the skin transmit information to the somatosensorycortex. Hence, option (b) is correct.
