2023年11月3日 · Lateral pterygoid is located deep to the temporalis and masseter muscles, spanning between the sphenoid bone and temporomandibular joint. Its muscle belly is separated by a small horizontal fissure into two heads; superior (upper) and inferior (lower).

The lateral pterygoid muscle (or external pterygoid muscle) is a muscle of mastication. It has two heads. It lies superior to the medial pterygoid muscle. It is supplied by pterygoid branches of the maxillary artery, and the lateral pterygoid nerve (from the mandibular nerve, CN V 3). It depresses and protrudes the mandible. When each muscle ...

The lateral pterygoid muscle is a craniomandibular muscle that helps control movement of the temporomandibular joint (TMJ). It has two heads, superior and inferior, and the inferior is three times larger than the superior.

2024年9月10日 · The lateral pterygoid muscle depresses the mandible and opens the mouth when assisted by the anterior belly of the digastric muscle and the mylohyoid muscle. Among all the four muscles of mastication (medial pterygoid, lateral pterygoid, masseter, and temporalis), the lateral pterygoid is the only muscle that participates in depressing the ...

2023年11月2日 · The lateral pterygoid is a short, two-headed muscle, located in the infratemporal fossa of the skull. The smaller superior head arises from the infratemporal crest of the greater wing of sphenoid bone , while the larger inferior head arises from …

2024年9月15日 · The lateral pterygoid muscle, also known as pterygoideus externus or external pterygoid muscle, is one of the muscles of mastication.

2023年1月16日 · The lateral pterygoid is a muscle of mastication (chewing). It is triangular shaped muscle with superior and inferior heads. Attachments: The superior head originates from the greater wing of the sphenoid. The inferior head originates from the lateral pterygoid plate of …

2024年7月13日 · The lateral pterygoid muscle is a key player in the movements of the mandible, specifically in opening the mouth and moving the jaw side-to-side. This article provides a comprehensive overview of the lateral pterygoid muscle, detailing its anatomy, function, and clinical significance.

2023年2月10日 · The lateral pterygoid muscle is a craniomandibular muscle that plays an essential role in the inferior temporal region. It is active during mastication and mandibular motions – including protrusion (forward movement of the mandible), abduction (depression of the mandible), and mediotrusion (mandibular condyle movement towards the midline).

The lateral pterygoid is a short, thick muscle, somewhat conical in form, which extends almost horizontally between the infratemporal fossa and the condyle of the mandible. It arises by two heads; an upper from the lower part of the lateral surface of the great wing of the sphenoid and from the infratemporal crest; a lower from the lateral ...
