What is the largest divison of the brain?
If the question is understood, the cerebrum is the largest part or portion of the brain. It contains billions of neurons. It is divided into two hemispheres. The longitudinal fissure delineates the right and left cerebral halves.
What area is posterior to the central sulcus?
Postcentral gyrus, or the parietal lobe [Edit: The postcentral gyrus is posterior to the central sulcus, not anterior. The primary motor cortex is located directly anterior to the central sulcus.]
What is a focal lesion on the temporal lobe?
Distinct damage to one area of the brain. The temporal lobe of the brain has many functions. Some of which: hearing and language processing and facial recognition. Depending on which hemisphere (right v. left) the damage occurs, the person can have many deficits in communication (esp. if on the dominant hemisphere, left for most people).
What is the location and of right hemisphere in the brain?
The human brain is divided in to the right and the left hemispheres. The right hemisphere (on the right side) of the brain controls the muscles on the left side of the body.
What part of the brain is damaged if the right side of the body is weak?
Its the left side of the brain that is injured As the right side of your brain controls the left side of your body as the left does your right.
What deep grove divides the brain into two hemispheres?
The medial longitudinal fissure divides the brain into left and right hemispheres.
What is the significance of the calcarine fissure as an anatomical marker?
The calcarine fissure is a complete sulcus at the caudal end of the medial surface of the brain. The visual cortex is found here at the back of the brain. The left side receives signals from the right eye and the right side receives signals form the left eye.
What does longitudinal fissure divide?
it separates the cerebrum into left and right hemispheres.
What is the prominent fissure that separates the cerebrum into right and left halves?
The most prominent division would be the "longitudinal fissure", which is that big line in the middle running anterior-posterior to the cerebral cortex. It was created before birth to give room to blood vessels to feed theWhen you dissect a brain you'll see those 2 sides connected by what looks like connective tissue, this tissue criss-crosses the nerves from back-to-front, meaning if you focus with your right eye, the message would be sent to the left back part of you brain. The second would be the the parieto-occipital sulcus, which really doesn't divide the brain but is constituted as a space in between, like a cave if you must. Another would be those to temporal lobes that pop out to the sides of the brain, looks like a helmet piece. Those are divided by the "lateral sulcus", your ears would be closest to it. The "transverse fissure" divides the cerebellum from the cerebrum. It runs all around the lower-back(inferior-posterior) part of the cerebrum. The pons look like balls, sits over the medulla oblongata which is the beginning of the brain stem(spinal cord). Gross fact: If you're a dude this might look familiar. -This is just the exterior stuff. Hope this helps
What are the two fissures of the right lung that divide it into a superior middle and inferior lobe respectively?
Horizontal fissure of the right lung and Oblique fissure of right lung.
Does the right lung have an oblique fissure?
Yeah it has an oblique and horizontal fissure
Where is lesion if you have normal vision in eyes right half but absence of vision in eyes on left half of visual field?
The lesion will be at the opposite of the absent vision of the eye which is the left eye.Marieb&Hoehn page 578A lesion of the right optic nerve causes a total loss of vision in the right eye. the lesion would be of the left optic nerve is the vision were to be reversed
The cerebrum is divided into left and right hemispheres by the?
The cerebrum is divided into left and right hemispheres by the corpus callosum. This structure allows for communication between the two hemispheres, enabling coordination and integration of information for various functions such as cognitive processing and motor control.
Can prostate cancer cause high blood pressure?
It depends where the lesion is. I had high blood pressure for years and didn't understand why because I was a cyclist and very fit. About three years ago I was diagnosed with brain cancer - I had 1 lesion on the right temporal lobe and a second on the pituitary gland. The pituitary lesion was removed and since then my blood pressure has been normal. The temporal lesion is still there because doctors can't remove it without killing me.
What is a sclerotic lesion in the right superior sacrum at inferior S1 vertebral level?
A .07 sclertoic lesion on my scarum which they say is stable. However, I have severe pain in that area and in my lower back and right leg. I have trouble walking or standing what does this mean.
What is the largest divison of the brain?
If the question is understood, the cerebrum is the largest part or portion of the brain. It contains billions of neurons. It is divided into two hemispheres. The longitudinal fissure delineates the right and left cerebral halves.
Deep groove that divides the right and left hemispheres of the cerebrum?
The deep groove that divides the right and left hemispheres of the cerebrum is the longitudinal fissure. It houses the falx cerebri, a fold of dura mater that helps separate the two hemispheres. The corpus callosum is a structure that connects the two hemispheres and allows for communication between them.
