What is a bacterial infection that causes rigid paralysis?
Tetanus (aka Lock Jaw) is caused by the bacterium Clostridium tetani. More specifically, it is the neurotoxin released by lysing bacteria (Tetanospasmin) that is responsible for the rigid paralysis.
Flaccid equals being rigid or firm is that true or false?
False. Flaccid is the opposite of rigid. For example, in the medical field, there's flaccid paralysis and rigid paralysis. Flaccid paralysis is when a body part is unable to be moved, but there is no muscle tone. The body part is "floppy." Rigid paralysis is when the body part is unable to be moved, but there is a lot of muscle tone. The body part is "stiff."
How calcium supplements useful in veterinary?
Calcium supplements are useful primarily to treat hypocalcemia. This is a nutritional issue that typically arises around pregnancy. In dogs, pregnancy hypocalcemia tends to be pre-parturient (before birth) and causes a tonic paralysis (rigid paralysis). In dairy cattle, hypocalcemia tends to be post-paturient (after birth) and causes a flaccid paralysis (floppy or loose paralysis). In both cases, careful administration of intravenous calcium can reverse the paralysis in a matter of hours.
What name is given to the rigid structure found outside the plasma membrane that surrounds and supports the bacterial cells?
The cell wall is a rigid supporting structure.
Which bacterial form can be curved like a spiral thick and rigid or thin and flexible?
The bacterial form that can be curved like a spiral can be either thick and rigid, known as spirilla, or thin and flexible, known as spirochetes. Both forms are capable of moving by rotating their bodies.
What kind of cell types usually has a rigid cell wall?
Collenchymatous cells have rigid cell wall
The transfer of genes during bacterial conjugation involves rigid tubular appendages called what?
They are called sex pili.
Why is your dogs neck swollen and his legs go stiff?
A swollen neck with tonic-clonic rigid paralysis of the legs is probably a medical emergency - this could be slipped vertebral disc in the neck or cancer around the spinal cord or brachial plexi.
What is rigor mortis and how would the onset of rigor mortis differ depending on the kind of neurotoxin the animals were exposed to?
Rigor mortis (literally "stiffness of death") is a natural process within the body after somatic death in which the skeletal muscles become locked in a contracted position. The carcass becomes rigid and unbending. Intoxication with a neurotoxin could affect the development of rigor mortis. For instance, tetanus toxin would cause the animal to be practically in rigor mortis at the time of death because it causes a spastic paralysis where the muscles are contracted during life. In contrast, botulinum toxin might cause the animal to have delayed rigor mortis or even to not develop a full rigor mortis because it blocks the nerves and causes a flaccid paralysis.
What is a cell wall mad of?
A cell wall is typically made of cellulose in plant cells and peptidoglycan in bacterial cells. These tough, rigid structures provide support and protection for the cell.
What is rigid or semi-rigid?
Rigid is immovable, unbending. Semi-rigid can move in a limited way.
Why does the lithosphere thicken away from the ridge crest?
Cooling as rock moves away from the ridge crest causes the rock to become increasingly rigid.
