physiology: functions of Brain lobes

Image
Certainly! The brain is divided into different lobes, each with its own specific functions. Here's a brief overview: 1 . **Frontal Lobe:* * Responsible for decision-making , problem-solving , planning, reasoning , and controlling emotional reactions. 2. ** Parietal Lobe: ** Handles sensory information like touch, temperature, and pain. Also involved in spatial awareness and perception. 3. ** Temporal Lobe :** Plays a role in processing auditory information, language comprehension, memory , and emotional responses. 4. ** Occipital Lobe :** Primarily responsible for processing visual information, interpreting shapes, colors, and motion. Remember that these descriptions are simplified, and brain functions are often interconnected across different regions. If you need more detailed information about each lobe's functions, feel free to ask! Read It Read My Text GIF from Read It GIFs Of course! Here are 10 multiple-choice questions (MCQs) related to the f

Lewis triple response

The Lewis triple response, also known as the "triple response of Lewis," is a physiological reaction that occurs when the skin is subjected to mechanical stimulation or irritation . It consists of three distinct components that appear sequentially when the skin is stroked or scratched. The Lewis triple response is often used as a diagnostic tool to assess the integrity of the nervous system , particularly nerve reflexes and blood vessel responses. The three components of the Lewis triple response are: Red Color GIF from Red GIFs 1. ** Red Line (Axon Reflex ):** The first component involves the immediate appearance of a red line along the path of stimulation. This red line is caused by the axon reflex, which is a rapid dilation of the small blood vessels (capillaries) in response to the mechanical stimulation. This dilation is mediated by local nerve reflexes that trigger the release of vasodilatory substances like histamine. 2. ** Flare (Axon
