How does stimuli sent in the brain?
Stimuli is anything that gives a reverse effect in our body or our body responds to it - positively or negatively.Our nerves are the means of contact in our body. All nerves connect to the primary nerve also known as the spinal cord. Nerve endings are found in every surface corner of our skin and scalp. Any momentary feeling in any of these places are carried by the respective nerve - to the spinal cord - to the brain stem to the brain. In the brain, there are many sectors , where different forms of stimuli are processed, mainly located in three primary divisions in the brain - cerebrum the back portion, cerebellum the top portion and medulla , the middle or the center. All of this is done in a nanosecond, which tells you what you are dealing with or what you are feeling.
What area includes the thalamus hypothalamus and epithalamus?
These are all part of the brain stem called the thalamus. The thalamus forms the floor of the third ventricle and along with the pons and the medulla oblongata forms the brain stem.
Why middle lamella is called cementing layer?

What is the smallest part of the human brain called?

Function of the Epithalamus?
its main function is to house the pineal gland (part of the endocrine system), which secretes melatonin. it also contains the choroid plexus of the third ventricle in the brain which forms cerebral spinal fluid.
What is the space enclosing the brain and spinal cord forms from a continuous cavity called?

What section of the spinal column forms part of the bony pelvis?

What is fourth ventricle?

What is a meninges?
The meninges, the singular is meninx, are the three membranes that surround and protect the brain. Just like our spinal column our brain is protected from damage by both bone, e.g. skull, and skin like membrane called the meninges.
Tissue that forms nerves and the brain?
Nervous (nerve) tissue.
What is brainstem?
The core of the brain - where the spinal cord attaches. Its also the thalamus - the oldest part of the brain (and the only part in old life forms like sharks).
Is the spinal cord contains nerve cells that carry information to and from the brain?
Yes; the brain is part of the Central nervous system itself, and the spinal cord forms a part of the nervous tissue itself. It is all one continuous tissue.
What is the membrane covering the brain and spinal cord called?
The myelin sheath forms a protective layer over nerves. However, it is not present on all nerves. Retinal nerves for instance normally are devoid of myelin.

Combined vertebral foramina forms the spinal canal. The spinal cord of the central nervous system is located within that canal.
What is the pathology of a meingioma brain tumor?
A meningioma brain tumour is a brain tumour which forms on the meninges which cover and protect the brain and spinal cord. They are slow growing and often show little to no symptoms. Some symptoms may include headaches, seizures and blurred vision.
What is syringomyelia?
Syringomyelia is a disorder where a cyst forms inside the spinal cord. This cyst, called a syrinx, grows over time, destroying a portion of the spinal cord from its center and expands outward
