The function of ligaments is connecting one bone to another bone, according to MedlinePlus. Ligaments also protect the joints from damage by limiting certain types of movements.Know More
The human body has more than 20 different ligaments, according to the University of Arkansas for Medical Sciences. They are found in the back, upper limbs, lower limbs, chest, abdomen, pelvis, head and neck.
One of the most well-known ligaments is the anterior cruciate ligament. The ACL connects the thigh bone to the tibia, which is found in the calf. The American Academy of Orthopaedic Surgeons estimates that approximately 200,000 ACL injuries happen each year.
A good way to see a ligament at work is to attempt to bend the elbow backward. Ligaments prevent this motion, reducing the risk of injury to the joint.Learn more in Biology
The mechanics of breathing involve the inhalation and exhalation of air into the lungs through the movement of the diaphragm muscle, according to MedlinePlus. The diaphragm contracts to expand the lungs, which draws air into them during inhalation. Then the diaphragm relaxes to reduce the size of the lungs, which forces air out of them during exhalation.Full Answer >
According to Materials Today, manufactured alloy steels can be 10 times better in tensile strength than bones and also 10 times better in fracture toughness and strain. Bones have a tensile strength of 150 MPa, a fracture toughness of 4MPa(m)1/2 and a strain-to-failure of 2 percent.Full Answer >
When a bone is soaked in acid, it loses its rigidity. Acids react with the calcium in bone; without calcium, bones become soft and pliable. This process occurs both in nature and in laboratory conditions.Full Answer >
According to Scientific American, peptidoglycan is the substance that makes up the cell walls of bacteria. The polymer is primarily composed of amino acids and sugars. Peptidoglycan is a crucial component of bacteria, and it influences several different facets of their biology. Scientists use differences in the peptidoglycan-based cell walls to classify different bacterial species.Full Answer >
