Textbook Question

A synarthrosis located between the bones of the skull is a
(a) Symphysis
(b) Syndesmosis
(c) Synchondrosis
(d) Suture

Verified step by step guidance

Understand the term 'synarthrosis': Synarthrosis refers to an immovable joint, which is a type of joint where bones are tightly connected and movement is not possible.

Review the anatomy of the skull: The bones of the skull are connected by immovable joints that are designed to protect the brain and provide structural integrity.

Analyze the options provided: Each option represents a type of joint. Symphysis involves fibrocartilage, syndesmosis involves ligaments, synchondrosis involves hyaline cartilage, and suture involves interlocking bone edges.

Match the correct type of joint to the skull: Sutures are the immovable joints found between the bones of the skull. They are characterized by interlocking edges that are held together by dense connective tissue.

Conclude that the correct answer is 'suture' based on the definition of synarthrosis and the anatomy of the skull.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Synarthrosis

A synarthrosis is a type of joint that is immovable. It is characterized by the absence of a joint cavity and is typically found in areas where stability is crucial, such as the skull. This type of joint allows for very little to no movement, providing strength and protection to the structures it connects.

Suture

A suture is a specific type of synarthrosis found between the bones of the skull. Sutures are fibrous joints where the edges of the bones interlock, providing a strong connection that allows for minimal movement. They play a vital role in protecting the brain and maintaining the shape of the skull.

Types of Fibrous Joints

Fibrous joints are classified into three types: sutures, syndesmoses, and gomphoses. Each type varies in the amount of movement allowed and the structure of the connective tissue involved. Understanding these distinctions is essential for identifying specific joints, such as recognizing that sutures are unique to the skull.
