Which of the following pairs of terms identify spaces that are roughly PERPENDICULAR (orthogonal) in the human brain (give or take 30 degrees or so)?
calcarine sulcus and central sulcus
What pairs?
calcarine sulcus and central sulcus
precentral sulcus and postcentral sulcus
superior temporal sulcus and inferior temporal sulcus
superior frontal sulcus and intraparietal sulcus
central sulcus and the parieto-occipital sulcus
Well, in the vast, convoluted universe of the human brain, there are a few pairs of spaces that could be considered roughly perpendicular, or as we like to say, at a wacky angle that could be around 30 degrees off. One such dynamic duo would be the superior sagittal sinus and the lateral ventricles. Just imagine them coming together to form a funky geometric dance move. Another pair would be the precentral gyrus and the postcentral gyrus, kinda like two neighboring party animals twisting and turning in opposite directions. But bear in mind, the brain is a complex labyrinth, so these relationships might not hold true in every situation. It's all part of the brain's quirky charm!
To find out which pairs of terms identify spaces that are roughly perpendicular in the human brain, we need to understand the structural organization and orientation of the brain.
The human brain is divided into different anatomical regions, each with its own specialized functions. These regions are interconnected by fiber tracts and divided into various spaces or planes. The main reference planes used in neuroanatomy are the axial, coronal, and sagittal planes.
Now, to determine which pairs of terms identify spaces that are roughly perpendicular in the human brain, we can consider the following:
1. The axial plane (also known as the transverse or horizontal plane) is perpendicular to the long axis of the body and divides the brain into superior (upper) and inferior (lower) parts.
2. The coronal plane (also called the frontal plane) is perpendicular to the axial plane and divides the brain into anterior (front) and posterior (back) parts.
3. The sagittal plane is perpendicular to both the axial and coronal planes. It divides the brain into left and right halves.
Given these orientations, if we consider pairs of spaces that are approximately perpendicular, we can identify the following pairs:
1. Axial plane and sagittal plane: The axial plane is roughly perpendicular to the sagittal plane, as it intersects the sagittal plane at a 90-degree angle.
2. Axial plane and coronal plane: The axial plane is also roughly perpendicular to the coronal plane. While it may not intersect the coronal plane at an exact 90-degree angle, it is close enough to be considered roughly perpendicular.
Therefore, the pairs of terms that identify spaces that are roughly perpendicular in the human brain are:
- Axial plane and sagittal plane
- Axial plane and coronal plane
