Summary
Persistent orofacial muscle pain (POMP) involves muscle, central nervous system, and coping factors. This review explores the complex interplay of elements contributing to POMP and dysfunction.
Area of Science:
- Neurology
- Pain Medicine
- Musculoskeletal Disorders
Background:
- The pathophysiology of persistent orofacial myalgia is controversial.
- Current understanding lacks a unifying descriptive term and comprehensive etiological model.
Purpose of the Study:
- To propose a novel descriptive term: 'persistent orofacial muscle pain' (POMP).
- To review evidence supporting a multifactorial hypothesis for POMP induction.
- To elucidate the interplay of factors contributing to POMP.
Main Methods:
- Literature review of current evidence.
- Synthesis of findings related to peripheral and central nervous system components.
- Analysis of psychological factors, including coping ability.
Main Results:
- Evidence supports a hypothesis involving peripheral nociceptive sources in muscle.
- A faulty central nervous system component is implicated in POMP development.
- Decreased coping ability is a significant contributing factor.
Conclusions:
- Persistent orofacial muscle pain (POMP) arises from a complex interaction of factors.
- Peripheral muscle issues, central nervous system dysfunction, and reduced coping ability are key elements.
- Understanding these factors is crucial for addressing POMP and dysfunction.

01:14Muscles for Facial Expressions
The craniofacial muscles are a collection of approximately 20 thin skeletal muscles situated beneath the skin of the face and scalp. These muscles, primarily responsible for the vast array of human facial expressions, originate from the bones or fibrous structures of the skull and extend outwards to connect with the skin. While most skeletal muscles in the body are enveloped in thick fascia, facial muscles generally have a more delicate fascial covering, with the buccinator muscle being a...
01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:26Muscles of the Anterior Neck
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...
01:14Cranial Nerves: Types Part I
Cranial nerves are responsible for transmitting motor and sensory information between the brain and various parts of the body. There are twelve pairs of cranial nerves, with the first six being essential in sensory perception, motor control, and autonomic functions related to the head and neck.
Olfactory Nerve (Cranial Nerve I)
The olfactory nerve, or cranial nerve I, is unique as it is purely sensory and dedicated to the sense of smell. This nerve originates in the olfactory epithelium of the...

01:11Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
01:17Accessory Structures of the Eye
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...
