21. Identify and describe the 3 primary brain vesicles formed from the neural tube.

Solutions

Expert Solution

The three primary brain vesicles that form from the neural tube forebrain or prosencephalon ,midbrain or mesencephalon and hindbrain or rhombencephalon.

Forebrain give rise to Telencephalon, Diencephalon.

The mid brain give rise to Mesencephalon.

And the hindbrain give rise to Metencephalon, and Myelencephalon.

FOREBRAIN :
It is the forwardmost portion of the brain. It plays a major role in controlling body temperature, reproductive functions, sleeping, display of emotions, eating.

MIDBRAIN:
The part of the brain that connects to hindbrain and the forebrain is called the midbrain or mesencephalon. The midbrain plays a major role in helping the movement as well as visual and auditory processing. Damage to the midbrain is associated with the development of Parkinson's disease.

HINDBRAIN:
It is the lowermost part of the brain. It includes medulla,pons and cerebellum.
The medulla and pons has sensory neurons that helps to transmit information from the spinal cord to the fore brain. The medulla also plays a major role in regulating the basic life functions such as respiration and heartbeat.

In newly formed neural tube, the intermediate region close to the sulcus limitans, has been not exposed to molecules that induce ventral or dorsal characteristics. You perform explant experiments in which you take intermediate neural tube (host tissue) and culture them with donor tissue explants that induce specific spinal cord markers in the host explant. 1. The induced host tissue express Shh following transplant. a. What donor tissue have you explanted next to the host tissue, what signal is released...
