The midbrain is a division of the brain alongside the forebrain and hindbrain. It is also referred to as the mesencephalon and it connects the forebrain to the hindbrain.
Please read on the Anatomy and Functions of the Forebrain here.
Present within the midbrain are various nuclei, nerves and tracts, each with an array of functions. In addition, visibly present on the midbrain are 4 bumps or swellings on its posterior (back) surface. These are referred to as the colliculi and are made up of aggregated neurons.
Note: The colliculi are separated into two pairs. These are:
The image below shows the midbrain's colliculi:
Please read on the Cerebellum, its Lobes and Functions here.
The midbrain is divided into 3 parts. These are:
The tegmentum consists of the iron-rich red nucleus (which appears pink in colour) and the periaqueductal grey (which is a composed mainly of grey matter).
Note: Functionally, the iron-rich red nucleus play a role in the body's coordination and movements. Also, the periaqueductal grey has proven to be important in the suppression of pain.
You may read on the Beauty of Suffering here.
Some of the important functions of the Midbrain include:
Movement of the eyes.
It regulates the dilation of the pupil.
It regulates sleep and wake cycles.
It controls our attentions and behaviour through the regulation of dopamine production.
You can read on the Uniqueness of Man here.
It assists in the regulation of temperature.
Please read on Homeostasis here.
It regulates muscular movements.
Please read on all 206 Bones of the Human Body here.
It is an important part of the memory.
It is important in the hearing process.
It helps to control our responses to sight.

It's crucial you finish your antibiotics.
If you stop taking your antibiotics before you're supposed to, any bacteria that didn't get killed can develop an immunity to that antibiotic and become a super-strain, making it much difficult to kill in the future. So keep taking your antibiotics pill, even if you feel better.
Although rare, women can still give birth when they die. This is known as coffin birth
Men can actually get aroused post moterm. This is called priapism

During strenuous exercises like sprinting or 🏃 running, your body may actually work in the shortage of oxygen. During this time, your body owes oxygen (called oxygen debt) and it must be replenished or repayed after the exercise is stopped. This is why you breathe excess of oxygen after you stopped the exercise.
This is the concept of anaerobic respiration
A food Chain is a diagram that shows the relationship between plants and animals within a habitat on the basis of how they rely on each other for food.
Note: Habitat is a place where an organism live. It is of three types:
The term Biology originated from two Greek words. They are:
