1. Central canal

Guida verificata passo dopo passo

Step 1: Identify the central canal in the cross-section of the spinal cord. The central canal is a small, circular space located in the center of the gray matter, which is shaped like a butterfly or the letter 'H'.

Step 2: Look for the label that points to the very center of the gray matter where a small hollow space is visible. This space is the central canal, which contains cerebrospinal fluid.

Step 3: Compare the labels a, b, c, d, and e to the anatomical structures. The central canal is not part of the white matter (outer region) but is within the gray matter (inner region).

Step 4: Confirm that the label pointing to the small central hollow space within the gray matter corresponds to the central canal. This is typically the smallest labeled structure in the center.

Step 5: Match the name 'Central canal' to the label that points to this central hollow space in the spinal cord cross-section.

Concetti chiave

Ecco i concetti essenziali che devi comprendere per rispondere correttamente alla domanda.

Central Canal

The central canal is a small, cerebrospinal fluid-filled channel located in the center of the spinal cord. It runs longitudinally through the spinal cord and is lined by ependymal cells. This canal is important for the circulation of cerebrospinal fluid, which cushions and nourishes the spinal cord.

Gray Matter of the Spinal Cord

The gray matter in the spinal cord is composed mainly of neuronal cell bodies, dendrites, and unmyelinated axons. It is organized into regions called horns: dorsal (sensory), ventral (motor), and lateral (autonomic). The gray matter processes sensory input and motor output.

White Matter of the Spinal Cord

White matter surrounds the gray matter in the spinal cord and consists primarily of myelinated axons. These axons form tracts that transmit signals between the brain and the rest of the body. The white matter is organized into columns or funiculi: dorsal, lateral, and ventral.
