What is a site for muscle or ligament attachment?

Entheses (insertion sites, osteotendinous junctions, osteoligamentous junctions) are sites of stress concentration at the region where tendons and ligaments attach to bone. Consequently, they are commonly subject to overuse injuries (enthesopathies) that are well documented in a number of sports.

What serves as a site for muscle or ligament attachment?

The spine (or spinous process) is a sharp, slender projection of the bone which is useful for attachment of muscles or ligaments.

What are muscle attachment sites called?

Muscles Attach to Bones At Locations Called Origins and Insertions. A skeletal muscle attaches to bone (or sometimes other muscles or tissues) at two or more places. If the place is a bone that remains immobile for an action, the attachment is called an origin.

What connects muscle to ligaments?

Tendons link your muscles to your bones. They let your bones move as your muscles tighten and relax.

Which is another term for sites of muscle or ligament attachment or projections?

Bone Markings

A B
Tuberosity (ligament & muscle attachment) Large rounded projection; may be roughened
Crest (ligament & muscle attachment) Narrow ridge of bone usually prominent
Trochanter (ligament & muscle attachment) very large, blunt, irregularly shaped process. (the only examples are on the femur.)

Which bone marking provides a site where bones articulate?

Bone Markings and FeaturesEdit

General Description Anatomical Term
Projections formed where tendons and ligaments attach Tuberocity
Tubercle
Projections formed where bones articulate with each other Capitulum
Condyle

What is a groove bone marking?

Groove – A furrow in the bone surface that runs along the length of a vessel or nerve, providing space to avoid compression by adjacent muscle or external forces. Examples include a radial groove and the groove for the transverse sinus. Head – A rounded, prominent extension of bone that forms part of a joint.

What are muscle insertions?

Muscle insertion refers to a muscle’s distal attachment—the end of the muscle furthest away from the torso. For example, the bicep insertion occurs at the elbow.

Where are the ligaments?

Ligaments are bands of tough elastic tissue around your joints. They connect bone to bone, give your joints support, and limit their movement. You have ligaments around your knees, ankles, elbows, shoulders, and other joints. Stretching or tearing them can make your joints unstable.

Do ligaments have origins and insertions?

There are two general categories of ligaments: intrinsic and extrinsic. Intrinsic ligaments have their origin and insertions within the carpus, with a large area of insertion onto cartilage rather than bone and much less elastic fibers compared with extrinsic ligaments.

What are alar ligaments?

The alar ligaments are fibrous cords that attach to the dens bilaterally and insert on the base of the skull. They function to limit axial rotation and lateral bending on the contralateral side, and flexion secondarily [1-2].

What does cartilage attach to?

Cartilage serves various purposes depending on its type and location in the body. Cartilage gives shape to organs like ears and nostrils, keeping them stiff but flexible. Cartilage attaches the ribs to the breast bone (sternum) and provides flexibility to the ribcage to allow expansion of the chest while breathing.

Where is the Iliofemoral ligament?

The iliofemoral ligament is the strongest ligament in the body and attaches the anterior inferior iliac spine (AIIS) to the intertrochanteric crest of the femur.

What muscle attaches to the iliofemoral ligament?

It is the origin of the straight head of the rectus femoris muscle, a flexor of the thigh at the hip, and an extensor of the knee. Its lower extent serves as the attachment site for the iliofemoral ligament.

Where does the ischiofemoral ligament attach?

Ischiofemoral ligament: It attaches to the posterior surface of the acetabular rim and labrum and courses circumferentially around the joint to its insertion on the anterior aspect of the femur. The ischiofemoral ligament limits internal rotation and hip adduction with flexion.

What are the attachments for the hip synovial capsule?

Ligaments. The hip joint contains a strong fibrous capsule that attaches proximally to the acetabulum and transverse acetabular ligament and distally to the neck of the femur anteriorly at the greater trochanter (see the image below).

Where does hip capsule attach?

The hip joint capsule is strong and dense, and is attached above to the acetabular margin 5-6 mm beyond its labrum, in front to the outer labral aspect and, near the acetabular notch, to the transverse acetabular ligament and the adjacent rim of the obturator foramen.

Where is the hip socket?

The socket area (acetabulum) is inside the pelvis. The ball part of this joint is the top of the thighbone (femur). It joins with the acetabulum to form the hip joint. The hip is one of the most stable joints in the body.

What muscle is attached to the hip bone?

Muscles and Tendons of the Hip Joint

There are three muscles (gluteus minimus, gluteus maximus, and gluteus medius) that attach to the back of the pelvis and insert into the greater trochanter of the femur.

What muscles attach to the femur?

The quadriceps include four large muscles, rectus femoris, vastus lateralis, vastus medialis, and vastus intermedius. The quadriceps femoris is one of the strongest muscle groups in the body that covers the anterior aspect of the femur. This group of muscles has a common function. They extend the leg at the knee joint.

Where does your hip flexor attach?

It originates at the anterior superior iliac spine and inserts superficially on the pes anserinus as a broad fascial insertion. It functions to flex the hip, and secondarily to adduct the thigh and externally rotate the leg.
