Types Of Body Moveme Flashcards
When describing movement, what are the five things to remember? Give example

Sagittal plane
Flexion does what to the angle and extension does what to the angle?
Flexion decreases the angle
Extension increases the angle

Lateral flexion is along which plane?
Coronal plane
Which parts of the body can perform lateral flexion?
- The lumbar spine
- Cervical vertebrae
Define adduction/abduction movement relative to the midline
Adduction is towards the midline
Abduction is away from the midline
Which joints can perfom adduction/abduction movement?
- Shoulder
- Hip
- MCP of fingers
- MTP of toes
- Carpo-metacarpal of thumb
Adduction and abduction movement is along which plane?
Coronal plane
Rotation movement is along which plane and axis?
Transverse plane
Longitudinal axis
Rotational movement is divided into two parts namely?
- Rotation of limbs
- Rotation of head and trunk
Rotation of limbs with reference to the midline is divided into two namely
External/lateral rotation
Internal/medial rotation
Which joints of the limb can perform rotation movement?
- Shoulder
- Hip
Rotation of the head and trunk is described based on 3 aspects namely? Give examples
- Rotation
- Organ
- Direction
Eg: Rotation of the head to the left
Which joints of the head and trunk can perform rotation movement?
- Cervical vertebrae
- Thoracic vertebrae
- A little- lumbar vertebrae
List the more common and important movements
- Flexion/ extension
- Lateral flexion
- Abduction/ adduction
- Rotation
Movements of the jaw include
1.Depression/ Elevation
2. Protrusion/ retrusion
Describe depression/ elevation movements of the jaw? Mention the joint involved
It is the superior inferior translation movement of the mandible
Joint is TMJ
Describe the protrusion/retrusion movement of the jaw
It is the anterior posterior translation movement of the mandible
Define protraction/retraction movement and give example
It involves protrusion and retrusion movement of jaw with lateral movement
Example cow chewing
Describe Circumduction
It is conical motion of the limbs
Which joints can perform circumduction?
- Shoulder
- Hip
- Fingers
- Thumb
Circumduction movement is a complex combination of which movements?
- Flexion
- Extension
- Adduction
- Abduction
Supination/pronation
Movement of the forearm at the Radioulnar joint
Which joints are involved in supination/pronation
Proximal and distal radioulnar joints
Supination is when
In anatomical position, When the radius is lateral to the ulnar
Pronation is
When the distal radius is medial to the ulnar and proximal radius remains lateral to the ulnar
Deviation movement happens only at which parts?
The wrist
Deviation is divided into two categories namely
Ulnar deviation
Radial deviation
Deviation defn
Movement of wrist ulnar and radius along the coronal plane with reference to the midline
Opposition/ reposition movement is done which joint?
The first carpometacarpal joint
The first carpometacarpal joint is also known as
Saddle joint
The CMC joint can perform which movement?
- Flexion/extension
- Abduction/ adduction
- Circumduction
- Opposition/reposition
Opposition/reposition movement defn
It is a compound movement that brings the thumb round and across the palm to press against other fingers and vice versa
Plantarflexion/ Dorsiflexion
Palmarflexion/ Dorsiflexion
Plantarflexion/ Dorsiflexion- Ankles
Palmarflexion/ Dorsiflexion- Wrist
Inversion/ eversion bones involved
Tarsals and tibia
Special movements of the upper limbs
- Circumduction
- Deviation
- Supination/ pronation
- Opposition/reposition
- Palmarflexion/Dorsiflexion
Special movements of lower limbs
- Circumduction
- Plantarflexion/dorsiflexion
- Inversion/ eversion
Special movements of the jaws
- Depression/elevation
- Protrusion/ retrusion
What is a joint
A joint is where two bones meet
How to classify joints
Based on two criteria
1. The range of motion
2. The type of tissue holding the bones together
Which criteria should a joint meet to become a synovial joint?
- Range of motion; should allow for a large range of motion
- Tissue holding the bones together; a) Both bones should have hyaline cartilage on their articulating surface, b) They should be enclosed in a capsule creating the joint cavity with synovial fluid
The articular capsule is made up of
Fibrous connective tissue
On the deep side of the articular capsule we find the?
Synovial membrane
Synovial membrane secrets?
Synovial fluid
Examples of synovial joints
- Shoulder
- Hip
- Sternoclavicular joint
- Proximal tibiofibular joint etc
Types of joints based on Axes of movement
- Uniaxial
- Biaxial
- Multiaxial
Ellipsoid joint is also known as
Condyloid joints
Describe ellipsoid joint
A rounded end of one bone articulates with a shallow depression of the other bone
Classify ellipsoid joint according to axes of movement
Biaxial joint
Example of ellipsoid joint
Metacarpophalangeal joint ( knuckes)
Give an example of saddle joint
1st CMC joint
Classify saddle joint according to axes of movement
Biaxial
Give an example of pivot joint
Atlanto-axial joint
Classify the pivot joint according to axes of movement
Uniaxial joint
Describe hinge joint
Convex end of one bone articulating with concave end of another bone
Hinge joint is biaxial, true/false
False, it is uniaxial
Example of hinge joint
Elbow: trochlear of humerus articulates with trochlear notch of the ulnar
Gliding joint is also known as
Plain joint
Examples of gliding joints
Intercarpal joints
Intertarsal joints
Gliding joints are uniaxial; true/false
False, they are multiaxial
Describe ball and socket joint
One bone has a ball articular surface , the other bone has a convex socket articular surface
Example of ball and socket joint
Shoulder ; head of hunerous and glenoid cavity of scapula
Ball and socket joint is biaxial joint; true/false
False, it is multiaxial
Mention types of synovial joints
- Ellipsoid joint
- Saddle joint
- Pivot joint
- Gliding joint
- Hinge joint
- Ball and socket joint
