Question

In human brain the sensation of touch, pain and temperature is controlled by the
A. Parietal lobe of cerebrum
B. Limbic lobe of cerebrum
C. Temporal lobe of cerebrum
D. Frontal lobe of cerebrum

Answer 1

Hint: The brain receives information through our five senses: sight, smell, touch, taste, and hearing. It assembles the messages, and may store that information in our memory. The brain controls our thoughts, memory and speech, movement of the arms and legs, and therefore the function of the many organs within our body.

Complete Answer:
The CNS consists of the brain and funiculus. The PNS consists of spinal nerves that branch from the funiculus and cranial nerves that branch from the brain.
 The brain consists of the cerebrum, cerebellum, and brainstem.
1. Cerebrum: Is the largest part of the brain and consists of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, still as speech, reasoning, emotions, learning, and fine control of movement.
2. Cerebellum: is found under the cerebrum. Its function is to coordinate muscle movements, maintain posture, and balance.
3. Brainstem: acts as a relay center connecting the cerebrum and cerebellum to the funiculus. It performs many automatic functions like breathing, heart rate, vital sign, wake and sleep cycles, digestion, sneezing, coughing, vomiting, and swallowing.

Lobes of the brain: The cerebral hemispheres have distinct fissures, which divide the brain into lobes. Each hemisphere has 4 lobes: frontal, temporal, parietal, and occipital. Each lobe is also divided, once again, into areas that serve very specific functions. It’s important to grasp that every lobe of the brain doesn't function alone. There are very complex relationships between the lobes of the brain and between the correct and left hemispheres.

a. Frontal lobe:
• Personality, behavior, emotions
• Judgment, planning, problem solving
• Speech
• Body movement
• Intelligence, concentration, self-awareness

b. Parietal lobe:
• Interprets language, words
• Sense of touch, pain, temperature (sensory strip)
• Interprets signals from vision, hearing, motor, sensory and memory
• Spatial and perception

Occipital lobe:
• Interprets vision (color, light, movement)

c. Temporal lobe:
• Understanding language
• Memory
• Hearing
• Sequencing and organization

Note:
- Cells of the brain: The brain is created from two forms of cells: nerve cells (neurons) and glial cells.
- Nerve cells: There are many sizes and shapes of neurons, but all comprises a cell body, dendrites and an axon. The neuron conveys information through electrical and chemical signals.
- Glial cells: Glia are the cells of the brain that provide neurons with nourishment, protection, and structural support.
