Hi Shafiya,

There are no types of a Cerebellum. Cerebellum has different different parts. It has 3 parts namely, the cerebrocerebellum, the spinocerebellum and the vestibulocerebellum.

• Cerebrocerebellum is the largest division formed by the lateral hemispheres.
• Spinocerebellum is comprised of the vermis and intermediate zone of the cerebellar hemispheres.
• Vestibulocerebellum is the functional equivalent to the flocculonodular lobe.

Feel free to ask doubts in the Comment Section.

I hope this information helps you.

Good Luck!

hello

according to syllabus its just Cockroach from the chapter structure of plants and animal but in exam there are chances to have question from frog and earthworm also i would suggest you to go briefly from all three topics and conc. littel more on cockroach

Hello

The heart function in a following ways :

The arteries receive oxygenated blood from heart and it supply it throughout the body . Whereas th veins carry the deoxygenated blood from all the part of our body to the heart for oxygenation.

The right atrium received blood from the veins and pump it to the right ventricle .

The right ventricle pump the blood to the lungs .

The left atrium received the oxygenated blood from the lungs and pump it to the left ventricle .

The left ventricle pumps the blood throughout the human body.

Good Luck

Hey there,

Cartilage is a special connective tissue. It is a flexible connective tissue that differs from bone in several ways; it is avascular and its microarchitecture is less organized than bone. It is of 3 types:

1. Hyaline Cartilage
2. Elastic Cartilage
3. Fibrous Cartilage

Hyaline Cartilage:

• The most widespread cartilage type and, in adults, it forms the articular surfaces of long bones, the rib tips, the rings of the trachea, and parts of the skull. This type of cartilage is predominately collagen (yet with few collagen fibers), and its name refers to its glassy appearance.
• It is the most widespread cartilage type and, in adults, it forms the articular surfaces of long bones, the rib tips, the rings of the trachea, and parts of the skull. This type of cartilage is predominately collagen (yet with few collagen fibers), and its name refers to its glassy appearance.

Elastic Cartilage:

• Elastic or yellow cartilage contains elastic fiber networks and collagen fibers. The principal protein is elastin.
• Elastic cartilage is found in the epiglottis (part of the larynx) and the pinnae (the external ear flaps of many mammals, including humans).

Fibrous Cartilage:

• Fibrous cartilage has lots of collagen fibers (Type I and Type II), and it tends to grade into dense tendon and ligament tissue. White fibrocartilage consists of a mixture of white fibrous tissue and cartilaginous tissue in various proportions.
• It is the only type of cartilage that contains type I collagen in addition to the normal type II.

Hope it helps.

Hello aspirant!
Hope you are doing well!

Well a cartilage bone is simply a bone that develops from cartilage rather than a fibrous tissue. Cartilage is a strong and flexible tissue found in human body specially around joints, bones, in nose In humans, specially adults it is mostly converted  into bone , remaining only on the articulating ends of bones, in the  , trachea , nose  , and ears

Hope it helps!

Hi, your answer;As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. These types of joints lack a joint cavity and involve bones that are joined together by either hyaline cartilage or fibrocartilage.

Hyaline cartilage which is found as the embryonic skeleton, costal cartilages, cartilage of the nose, trachea, lining of the ends of some bones and the larynx. Elastic cartilage which is found in the external ear and epiglottis.

I hope you have got your answer.

Good Luck.

Dear aspirant,

Bone is a connective tissue made mostly of collagen. It is a living and growing tissue. Collage is a protein that provides a soft framework. Calcium Phosphate is also found in bones which which adds strength and hardens the framework. More than 99% of the calcium in body is present in bones and teeth.

Bones are of 2 types:

• Cortical
• Trabecular

Cortical bone is dense and compact and forms the outer layer of bone. Trabecular bone is spongy and has honeycomb like structure and forms inner layer of cell.

Bone forms the framework of our body and provide our muscles support. Bones protect our internal organs also from damaging. In this way bones are very helpful to us.

Hope this helps.

Bone, rigid body tissue consisting of cells embedded in an abundant hard intercellular material. The two principal components of this material, collagen and calcium phosphate, distinguish bone from such other hard tissues as chitin, enamel, and shell.

Hope this will help you.
