Concept explainers
(a)
To name: The cerebral cortex area that directs perception.
Introduction: Brain is the most important and complex part of the nervous system. The brain of vertebrates consists of three major divisions, which are forebrain, midbrain, and hindbrain. The outermost region of the brain is termed as forebrain, the middle region is called midbrain, and the innermost part is known as the forebrain. The forebrain contains an area known as the cerebrum, which is composed of the cerebral cortex.
(b)
To name: The cerebral cortex area that directs movement.
Introduction: Nervous system is a system in the body that helps in the transfer of information from one part to the other. The body parts communicate with each other and with the external environment through the nervous system. Brain is the most important organ in the nervous system. Brain guides all the other organs in the body. Humans have the most complex brain. Cerebral cortex is a part of the brain.
(c)
To name: The cerebral cortex area that integrates information and directs voluntary behaviors.
Introduction: Forebrain, midbrain, and hindbrain are the three major parts of the brain. Every part performs a unique function and helps in the normal functioning of the brain. The cerebral cortex is present inside the forebrain region. The cerebral cortex is divided into three major parts, which are the sensory area, the motor area, and the association areas.
