Question

1. Как построен спинной мозг рыб? ​

Answer 1

Ответ:

Спинной мозг - у рыб представляет собой трубку, полость которой окружается скоплениями нервных клеток, тогда как волокна (белое вещество) располагаются по периферии. У некоторых рыб спинной мозг не доходит до конца канала

Answer 2

Structure of the Spinal Cord in Fish

The spinal cord in fish is an essential part of their central nervous system. It is responsible for transmitting sensory information from the body to the brain and coordinating motor responses. While I couldn't find specific information on how the spinal cord is constructed in fish, I can provide some general information about the spinal cord's structure.

The spinal cord is a long, tubular structure that runs along the vertebral column, which is the backbone of the fish. It is protected by the vertebral column and is surrounded by cerebrospinal fluid, which provides cushioning and support. The spinal cord consists of gray matter and white matter.

Gray matter is located in the center of the spinal cord and contains cell bodies, dendrites, and synapses. It is responsible for processing and integrating sensory information and coordinating motor responses. The gray matter is divided into different regions, including the dorsal horn, ventral horn, and lateral horn.

White matter surrounds the gray matter and consists of myelinated nerve fibers. These fibers form tracts that carry sensory information from the body to the brain and motor commands from the brain to the muscles. The white matter is divided into ascending tracts, which carry sensory information to the brain, and descending tracts, which carry motor commands from the brain to the muscles.

The spinal cord is connected to the brain through the medulla oblongata, which is the lower part of the brainstem. This connection allows for the transmission of information between the spinal cord and the brain.

Unfortunately, I couldn't find specific information on how the spinal cord is constructed in fish. If you need more detailed information, I recommend consulting scientific literature or textbooks on fish anatomy and neurobiology.
