The sensory cortex is most critical for our sense of touch. Which of the following body parts is associated with the greatest amount of brain tissue in the motor cortex? motor cortex.
Which body part is associated with the greatest amount of brain tissue in the motor and somatosensory cortexes?
Explanation: Lips is the part of the skin which can feel the sensations such as touch, heat, pressure and it covers the greatest amount of brain tissue. Somatosensory system is distributed throughout the major parts of the body. It is responsible for the sensations in the body.
What parts of the body have the greatest amount of cortex devoted to them?
The areas of skin with the higher density of receptors (like the face, hands and fingers) have more cortical tissue devoted to them.
Which stroke has affected the greatest amount of brain tissue?
Types of stroke
The force of blood that escapes from the blood vessel can also damage surrounding brain tissue. Hemorrhagic stroke is the most serious kind of stroke. About 13% of all strokes are hemorrhagic. There are two types of hemorrhagic strokes: intracerebral and subarachnoid.
Which of the following is located in the temporal lobes *?
Important structures within the temporal lobes include the olfactory cortex, the hippocampus, Wernicke’s Area, and the amygdala.
What body part has the greatest amount of brain tissue?
|A neuroscientist should electrically stimulate what part of a rat’s brain if he or she wishes to elicit an aggressive response?||amygdala|
|Which of the following body parts is associated with the greatest amount of brain tissue in the sensory cortex?||lips|
Which part of your brain receives information that you are moving your legs?
One of the brain areas most involved in controlling these voluntary movements is the motor cortex. The motor cortex is located in the rear portion of the frontal lobe, just before the central sulcus (furrow) that separates the frontal lobe from the parietal lobe.
Which part of the brain is bigger?
The cerebrum, consisting of the cerebral hemispheres, forms the largest part of the brain and overlies the other brain structures.
Which motor area both has a homunculus?
The cerebellum has a cortex and homunculus, just like the motor cortex.
Which part of the brain is associated which emotions and urges?
The limbic system is a group of interconnected structures located deep within the brain. It’s the part of the brain that’s responsible for behavioral and emotional responses.
Which type of stroke is associated with blockage?
An ischemic stroke occurs when a blood vessel that supplies the brain becomes blocked or “clogged” and impairs blood flow to part of the brain. The brain cells and tissues begin to die within minutes from lack of oxygen and nutrients.
What part of brain is damaged with stroke?
A stroke normally effects one side of the brain. The left side of the brain controls the right side of the body and the right side of the brain controls the left side of the body. If there’s a lot of damage to the left side of the brain, you may experience paralysis on the right side of the body.
Do strokes kill brain cells?
A stroke occurs when a blood vessel in the brain bursts or gets clogged. Clots that block an artery cause ischemic strokes. This is the most common type of stroke and accounts for 85% of all strokes. Millions of brain cells die each minute a stroke is untreated.
What are the temporal lobes responsible for?
The temporal lobes sit behind the ears and are the second largest lobe. They are most commonly associated with processing auditory information and with the encoding of memory.
Which senses are affected by damage to the temporal lobe?
Kolb & Wishaw (1990) have identified eight principle symptoms of temporal lobe damage: 1) disturbance of auditory sensation and perception, 2) disturbance of selective attention of auditory and visual input, 3) disorders of visual perception, 4) impaired organization and categorization of verbal material, 5) …
What are the 4 lobes and their functions?
Each side of your brain contains four lobes. The frontal lobe is important for cognitive functions and control of voluntary movement or activity. The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
