MUSCLE PHYSIOLOGY

Detailed explanation-1: -Superficial pain arises from nociceptive receptors in the skin and mucous membranes. It is the type of pain that happens with common everyday injuries-for example, if you cut your lip.

Detailed explanation-2: -Somatic pain is often divided into two forms. The first, called superficial pain, occurs when pain receptors in the skin, mucus, and mucous membranes are activated. Common, everyday injuries usually cause superficial somatic pain. The second form of somatic pain is known as deep somatic pain.

Detailed explanation-3: -Pain is generally considered acute when it lasts fewer than three months. Acute pain typically starts suddenly in response to an injury-a cut, bruise, burn, broken bone, or pulled muscle, for example. Acute pain can also be caused by a fever or infection, labor contractions, and menstrual cramps.

Detailed explanation-4: -Nociceptive pain. Nociceptive pain is the most common type of pain. It’s caused by stimulation of nociceptors, which are pain receptors for tissue injury.

Detailed explanation-5: -The acute phase of pain is one to four days after a severe injury or a severe medical condition and up to seven days following a major surgical procedure or trauma. Use caution when prescribing opioids even in this timeframe, given the potential for patients to experience harm related to any new opioid prescription.
