Fish anatomy - Wikipedia
WEBFish are vertebrates. All vertebrates are built along the basic chordate body plan: a stiff rod running through the length of the animal (vertebral column or notochord), [8] with a hollow tube of nervous tissue (the spinal cord) above it and the gastrointestinal tract below.
Fish Brains: Anatomy, Functionality, and Evolutionary …
WEBJul 2, 2020 · The fish spinal cord is the phylogenetically oldest part of the CNS and hence, similar in structure to the spinal cords of all other vertebrates. During embryonic development, the CNS forms when neural folds roll in and fuse (Nieuwenhuys et al. 1998 ).
Structure of Spinal Cord in Fishes (With Diagram) - Your Article …
WEBThe basic structure of spinal cord in fishes resembles to that of higher vertebrates. It runs dorsal and lengthwise of the fish body in the neural canal of the vertebral column. In transverse section of spinal cord two regions are clearly distinct, i.e. central and peripheral.
Zebrafish regenerate their spinal cords in a surprising way
WEBAug 15, 2024 · The atlas tells scientists how these special fish can fully heal a severed spinal cord and could offer clues on how to develop healing strategies for human spinal cord injuries.
Spinal cord repair is modulated by the neurogenic factor Hb
WEBAug 11, 2023 · Unlike adult mammals, zebrafish regenerate spinal cord tissue and recover locomotor ability after a paralyzing injury. Here, we find that ependymal cells in zebrafish spinal cords produce the...

WEBThe vertebrae bones protect the spinal cord. Spaces between the vertebrae allow the backbone to bend and nerves to reach the tissues and organs of the body. Rib bones protect the body cavity.
Regenerative Medicine: New Clue from Fish about Healing Spinal Cord ...
WEBNov 15, 2016 · When the fish’s spinal cord is severed, something remarkable happens that doesn’t occur in humans: supportive cells in the nervous system bridge the gap, allowing new nerve tissue to restore the spinal cord to full function within weeks.
Fish Nervous System: How The Brain & Nerves Work | Earth Life
WEBMar 19, 2020 · The nervous system of fish (much like ours) is composed of a central coordinating brain, a spinal cord, and many, many nerves. These nerves send electrical impulses to and from the brain, telling the fish what to do.
Know How to Regrow—Axon Regeneration in the Zebrafish Spinal Cord
WEBJun 6, 2021 · Here, we review the spinal cord injury paradigms used in zebrafish, and summarize the breadth of neuron-intrinsic and -extrinsic factors that have been identified to play pivotal roles in the ability of zebrafish to regenerate central nervous system axons and recover function.
