What is the function of shivering?
Shivering is an involuntary muscular response from the body, triggered by cold. The "shivering" muscles are trying to internally generate heat, to help keep you warm.
What is the humerous?
It is the upper forelimb bone of any tetrapod.
Why do you have a Stronger grip when the wrist is extended as compared to when the wrist is flexed?
It's about Strength Potential. When your muscles contract and shorten to flex the wrist, they lose the potential to contract more, thus they lose the abililty to create a stronger grip past a certain level. As grip is mostly a function of the muscles that flex, thus the more flexed your are, the less strength potential you have.
Why should you not overtire your muscles?
Muscles should not be overworked because that can result in tearing of the muscles and muscle strain. It can also lead to other injuries like pulled muscles and sprains.
What organs are found in the Muscular System?
The main organs found in the human body's muscular system are the cardiac muscles, smooth muscles, and skeletal muscles.
Ridges in anterior wall of right atrium are called?
Pectinate muscles
The internal wall surface of each ventricle displays large smooth irregular muscular ridges called?
pectinate muscles
What muscle is found in the right atrium?
The type of muscle that is found in the right atrium is mainly the pectinate muscles. This is one of the four chambers of the heart.
What is the Difference between the papillary muscle and the pectinate muscle?
The pectinate muscles are shaped a bit like brush bristles, and their function is to allow maxium contraction of the atria using the minimal muscle mass. Papillary muscles are connected to strong tendons in the ventricles called the chordae tendinae, which gives them a lot of strength. Their purpose is to prevent prolapse of the valves in the ventricles after the ventricles contract. Prolapse means that the valves fall inward, allowing backflow of blood back into the ventricles after they have contracted, which makes for a far less efficient action of the ventricles. Prolapsed valves and the blackflow of blood caused by the valves folding onto themselves is called a "heart murmur".
What chamber is pectinate mm found in?
Atria of the Heart
Function of each organ of muscles?
There is no such thing as an "organ of muscles".
What is the difference between Hilton white line and the pectinate line?
Hilton's white line is slightly below the pectinate line. The transition of epithelium at Hilton's white is from non-keratinising squamous to keratining squamous while at the pectinate line it is coloumnar to non-keratinising stratified squamous. Also Hilton's seperates the venous drainage from potal to systemic while pectinate line seperates arterial supply from inf. mesenteric to internal pudendal. Second year med student
