Aug 8, 2023 · Put simply, the main four functions of the pulp are formation and nutrition of the dentin, as well as the innervation and defense of the tooth. Dentin formation is one of the most critical roles carried out by the pulp and, as mentioned, is formed by the odontoblasts.

Jun 4, 2020 · The dental pulp is closely associated with dentin and harbors odontoblasts, dental pulp stem cells (DPSCs), pericytes, and other cellular populations. Blood vessels penetrating the pulp nourish the resident cells, while nerves participate in the sensory information exchange between the pulp and oral environment ( Figure 1 B).

Your amazing, versatile, complicated body is tougher than it looks. Between your muscles, skin, cartilage, and bones, your vital organs are surrounded by a structural force field that doubles as an engineering marvel.
So what’s the hardest substance in your body? The answer might surprise you. In fact, the most durable and tough substance in your body is actually a tissue.
Encasing your teeth and helping you chew, bite, and tear your food is your tooth enamel. That’s the hardest substance in the human body.
Keep reading to learn more about enamel and other strong elements in your body.
Enamel is one of four types of tissue that make up your teeth. The other three types are:
•dentin
•cementum
•pulp
You might have assumed that bones are the hardest substance in your body. And bones are incredibly tough, also earning a 5 on the Mohs Hardness Scale.
Bones are considered to be stronger than concrete. Fun fact: the jawbone and the femur are considered the strongest bones in your body.
Bone is made of living tissue. Collagen and a mineral called calcium phosphate make up most of your bone structure.
•Cortical bone tissue is dense, and it makes up the outer layers of your bones.
•Trabecular bone tissue is the spongy, honeycomb-like material that makes up your inner bones.
The unique composition of your bones is what makes them strong and resilient, but flexible enough to absorb some stress.
Muscles
Muscles are made of thousands of highly flexible fibers. Muscles help your bones to move, and also form the walls that surround your organs. Muscles fibers are bound together tightly in groups, which is what gives them their strength.
Ligaments
Ligaments are made of strong, connective collagen tissue. These bands of tissue are used to hold your joints together and keep your muscles in place throughout different parts of your body. Ligaments are like ropes that keep your muscles from over-extending their reach.
Tendons
Tendons are also made of connective collagen fibers. Tendons are what connect your muscles to your bones. Tendons are more flexible than ligaments. They also contain fewer blood vessels than your muscles, which makes them more prone to injury. Muscles, ligaments, and tendons are incredibly strong, and have varying degrees of elasticity. But they aren’t particularly hard, and would rank low on Mohs scale.
Your teeth contain the hardest substance in the human body — your enamel.
Bones aren’t quite as hard as enamel, but they rank closely on the hardness scale.
Both parts contain an inner pulp cavity, containing loose connective tissue through which run nerves and blood vessels. The region of the pulp cavity that runs through the root of the tooth is called the root canal.

Sep 12, 2022 · The rest of the bolus is pushed back towards the body of the stomach for further mechanical and chemical digestion. This backward movement of the bolus from the pylorus to the body is termed retropulsion and aids in mechanical digestion.

Chemical digestion breaks large food molecules down into their chemical building blocks, which can then be absorbed through the intestinal wall and into the general circulation. Intestinal brush border enzymes and pancreatic enzymes are responsible for the majority of chemical digestion.
