Common Attachment Points Flashcards
1
Q
What are common attachment points?
A
- the areas where tendons or ligaments attach to bones in the human body
- important for connecting muscles to bones & providing stability & movement
2
Q
What are tuberosity’s? And what are 2 examples?
A
- large, rounded prominence on a bone where tendons or muscles attach
- greater tuberosity of humerus & tibial tuberosity
3
Q
What is the greater tuberosity of the humerus?
A
- on the lateral side of the humerus
- an attachment point for the muscles of the rotator cuff (supraspinatus, infraspinatus, teres minor, subscapularis)
- provides movements of the shoulder like abduction, external rotation & stabilization
4
Q
What is the tibial tuberosity?
A
- located on the anterior surface of the tibia
- an attachment point for tendons & ligaments that provide knee movement & stability
- attachment for the patellar ligament which is a continuation of the quadriceps tendon and allows attachment for the quadriceps muscles
- common condition is osgood-schlatter disease
5
Q
What are crests? What are 2 examples?
A
- a prominent ridge on a bone where muscles or tendons attach
- iliac crest & epicondyle
6
Q
What is the iliac crest?
A
- a curved structure that extends from the ASIS to the PSIS
- serves as an attachment point for several muscles involved in hip movement, stabilization, & those that support the trunk & lower back
- muscle attachments include external/internal abdominal obliques, gluteus medius, latissimus dorsi, & the erector spinae group
7
Q
What are epicondyles?
A
- 2 prominent bony projections located at the distal end of the humerus (lateral/medial)
- serve as attachment points for muscles & ligaments that involve movement & stability of the elbow
8
Q
What is the medial epicondyle of the humerus?
A
- located on the inner side of the distal humerus (larger than the lateral epicondyle)
- an attachment point for all the flexor muscles of the wrist and hand
- attachment point for the ulnar collateral ligament (provides stability & prevents excessive side-to-side movement)
- an injury/condition involved is golfer’s elbow
9
Q
What is the lateral epicondyle of the humerus?
A
- bony prominence located on the outer side of the distal humerus (smaller than the medial epicondyle)
- serves as an attachment point for all the extensor muscles of the wrist & hand
- an attachment point for the radial collateral ligament (provide stability for the outer side, prevents excessive side-to-side movement)
- an injury/condition is tennis elbow
10
Q
What is a trochanter? What are 2 examples?
A
- refers to a bony prominence or projection of the femur
- the femur has 2 trochanters; the greater trochanter & the lesser trochanter
- serve as attachment points for muscles & play important roles in hip movement & stability
11
Q
What is the greater trochanter of the femur?
A
- large bony prominence on the lateral side of the proximal femur
- attachment point for the gluteus medius/minimus & the external rotators of the hip
12
Q
What is the lesser trochanter?
A
- smaller bony prominence located on the Posteromedial femur
- can’t palpitate as easy as the greater trochanter
- attachment point for the iliopsoas which consists of the psoas major & ilacus which flex the hip
- attachment point for the pectineus & some fibres of the adductor Magnus
13
Q
What is the spinous process?
A
- sharp, projecting structure that extends posteriorly from the vertebral arch of a vertebra,become larger in the lower regions
- present in each vertebra of the spine (cervical, thoracic, & lumbar spine)
- attachment points for several muscles, ligaments, & connective tissues which are crucial in providing stability, movement, & maintaining proper alignment of the spine
- misalignment or abnormal position can cause scoliosis
14
Q
What are 4 examples of attachment points for the spinous process?
A
- erector spinae muscles (maintain upright posture, control spinal movement, provide stability)
- ligamentum flavum (helps maintain normal curvature of the spine, and limits excessive flexion)
- interspinous ligaments (provide stability, limit excessive extension)
- muscles of neck & upper back (head & neck movement, upper back stabilization)
15
Q
What is scoliosis ?
A
- a medical condition characterized by abnormal curvatures of the spine that forms an “S” or “C” shape
- there are 4 types of scoliosis
