Which Animals Have A Dorsal Nerve Cord?

Where Is The Dorsal Stream? Also known as the parietal stream, the “where” stream, or the “how” stream, this pathway stretches from the primary visual cortex (V1) in the occipital lobe forward into the parietal lobe. What makes up the dorsal stream? The dorsal stream, or where pathway, describes a hierarchy of areas that support
Where Is The Dorsal Hollow Nerve Cord? The dorsal hollow nerve cord derives from ectoderm that rolls into a hollow tube during development.

How Do You Describe Body Positions? The Need for Standardization. Standard anatomical position is the body orientation used when describing an organism’s anatomy. … The front of the body is referred to as anterior or ventral, while the back is referred to as posterior or dorsal.
