Could you see them on the microscope slide of the spinal cord cross section?
Cross sections of the spinal cord are so large that you will not be able to see the whole thing on the microscope–you will have to move back and forth or use a dissecting microscope. You can see the gray matter (lighter color) in the center of the spinal cord and the white matter (darker color) around the outside.
What is the cross section of spinal cord?
A cross section of the spinal cord reveals white matter arranged around a butterfly-shaped area of gray matter. The white matter consists of myelinated fibres, or axons, that form nerve tracts ascending to and descending from the brain. The white matter is grouped into discrete sectors called funiculi.
What is spinal cord smear?
A cerebrospinal fluid (CSF) smear is a laboratory test to look for bacteria, fungi, and viruses in the fluid that moves in the space around the spinal cord and brain. CSF protects the brain and spinal cord from injury.
What makes up the white matter you viewed on the slide?
White matter is named for its relatively light appearance resulting from the lipid content of myelin. However, the tissue of the freshly cut brain appears pinkish-white to the naked eye because myelin is composed largely of lipid tissue veined with capillaries….
What are the three sections of the spine called?
The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.
Is cross section and transverse section the same?
Essentially, they mean the same with a slight difference. The cross section lies within the body while the transverse may include inside/outside of the body.
What is a cross section in math?
A cross-section is a plane section that is a section of a three-dimensional object that is parallel to one of its planes of symmetry or perpendicular to one of its lines of symmetry. Describe shapes formed by cross-sections (square, rectangle, triangle, etc).
