List the three abnormal contractions of muscles we went over in lecture.Explanation / Answer
Answers :-
36.option 'b'-ATP.
37.option 'a'-True-bone is made up of living cells. Bones in our body are living tissue. They have their own blood vessels and are made of living cells, which help them to grow and to repair themselves. As well, proteins, minerals and vitamins make up the bone. We are born with about 300 soft bones.
38.option 'a'- repair broken bones.
Bone Remodeling and Repair. ... Bone remodeling is the replacement of old bone tissue by new bone tissue. It involves the processes of bone deposition or bone production done by osteoblasts and bone resorption done by osteoclasts, which break down old bone.
39.option 'a'-ligaments.
a short band of tough, flexible fibrous connective tissue which connects two bones or cartilages or holds together a joint.
40.option 'b'-tendon.
a flexible but inelastic cord of strong fibrous collagen tissue attaching a muscle to a bone.
41.part-A-
Tetanus is caused by the soilborne, anaerobic, Gram-positive rodClostridium tetani. Spores of this organism enter a wound, where they germinate to vegetative cells. The organisms produce a powerful exotoxin that interferes with the removal of acetylcholine from the synapses in the nervous system.
Botulism is a serious illness that causes flaccid paralysis of muscles. It is caused by a neurotoxin, generically called botulinum toxin, produced by the bacterium Clostridium botulinum (and rarely by C. butyricum and C. baratii). There are seven distinct neurotoxins (types A-G) that Clostridium botulinum produces, but types A, B, and E (and rarely F) are the most common that produce the flaccid paralysis in humans.
Part-B:-
1.
abnormal contractions of skeletal muscle may be cause by holding a position for a prolonged period cramp.
2.
abnormal contraction of skeletal muscle is caused by a twitch of an entire motor unit and is visible under the skin fasciculation.
3.
abnormal contraction of skeletal muscle is caused by a single muscle fiber, is spontaneous and is not visible under the skin fibrillation.
