2023年11月2日 · Medial pterygoid muscle (Musculus pterygoideus medialis) The medial pterygoid muscle is a thick quadrilateral muscle that arises by two heads, a superficial and a deep head. The smaller superficial head originates from the maxillary tuberosity and pyramidal process of …

Pterygoid, from the Greek for 'winglike', may refer to: Pterygoid bone, a bone of the palate of many vertebrates; Pterygoid processes of the sphenoid bone Lateral pterygoid plate; Medial pterygoid plate; Lateral pterygoid muscle; Medial pterygoid …

The medial pterygoid muscle (or internal pterygoid muscle) is a thick, quadrilateral muscle of the face. It is supplied by the mandibular branch of the trigeminal nerve (V). It is important in mastication (chewing). The medial pterygoid muscle consists of two heads.

The pterygoid processes of the sphenoid (from Greek pteryx, pterygos, "wing"), one on either side, descend perpendicularly from the regions where the body and the greater wings of the sphenoid bone unite.

2023年11月3日 · Lateral pterygoid is a two-headed, fan-shaped muscle located laterally in the infratemporal fossa of the skull. It is one of the four masticatory muscles, along with the medial pterygoid, temporalis and masseter muscles. All these muscles act upon the temporomandibular joint (TMJ) to enable chewing (mastication) and biting.

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 inferior belly, also known as the pterygoid head, is three times larger than the superior belly and anteriorly attaches on: the inferior two-thirds of the lateral area of the pterygoid process' lateral wing, lateral area of the pyramidal process, and part of the maxillary bone tuberosity.

2024年10月1日 · The muscles of mastication are a group of muscles associated with movements of the jaw. There are four muscles - the masseter, temporalis, medial pterygoid and lateral pterygoid.

2023年6月5日 · The medial pterygoid muscle, a major elevator of the jaw is a square-shaped masticatory muscle, located on the medial aspect of the lower jaw bilaterally. It is also known as internal pterygoid muscle. This muscle lies medial to the lateral pterygoid muscle.

2023年11月3日 · Medial pterygoid is a thick quadrilateral muscle that connects the mandible with maxilla, sphenoid and palatine bones. It belongs to the group of masticatory muscles, along with the lateral pterygoid, masseter and temporal muscles. Medial pterygoid muscle consists of two heads; superficial and deep. Although having different origins, both heads ...
