Title: Musculoskeletal Anatomy


1
Musculoskeletal Anatomy
  • Toby J. Brooks, PhD, ATC, CSCS

2
Anatomical Kinesiology Foundations
  • What the heck is it?
  • The study of muscles as they are involved in the
    science of movement
  • Who needs to learn about it?
  • Why do I need to take it?

3
Overview
  • Directional terminology
  • Planes of motion
  • Axes of rotation
  • Types of bones
  • Types of joints

4
Foundations
  • Directional terminology
  • Must be familiar with directional termswe will
    use them everyday and it is assumed you learned
    these terms in prerequisite courses (namely A
    P)
  • Review terms on pages 3-5

5
Foundations
  • Group assignment
  • Start at the belly button. Move laterally about
    one hand width to the right. Then move inferiorly
    and distally until you reach a hinge joint. Move
    to the posterior side of the joint and travel
    distally until you reach a large tendon. Move to
    the contralateral side (continued)

6
Foundations
  • Travel superiorly past a hinge joint and a ball
    and socket joint, up the dorsal surface until you
    reach another ball and socket joint. Move to the
    anterior side and medially about two hand widths.
    You are now over a large flat bone. Move
    superiorly approximately two hand LENGTHS, then
    move to the right, lateral-most aspect of this
    structure.

7
Foundations
  • Where are you?
  • Right ear

8
Foundations
  • Planes
  • Frontal or Coronal
  • Divides body into anterior and posterior portions
  • Sagittal
  • Divides body into left and right portions
  • Transverse or horizontal
  • Divides body into inferior and superior portions

9
Planes
Frontal/AP Sagittal Transverse
10
Axes of Rotation
  • Sagittal/AP
  • Lateral
  • Vertical

11
Types of Bones
  • Long
  • Ex.- Femur
  • Short
  • Ex.- calcaneus
  • Flat
  • Ex.- Scapula

12
Types of Bones
  • Irregular
  • Ex.- Spine
  • Sesamoid
  • Ex.- Patella

13
Types of Joints
  • Synarthroidial (immovable)
  • Example Cranial sutures

14
Types of Joints
  • Amphiarthroidial (slightly movable)
  • Syndesmosis
  • Ex.- tib./Fib
  • Synchondrosis
  • Ex.- symphysis pubis

15
Types of Joints
  • Diarthrodial
  • Arthrodial (gliding)
  • Condyloidal (ball socket)
  • Enarthodial (multiax. ball socket)
  • Ginglymus (hinge)
  • Sellar (saddle)
  • Trochoidal (pivot)
