Exam #1 - Foundational Concepts Flashcards
What is the Movement System
- A physiologic system that functions to
produce motion of the ____ ____ or of its ____ ____ - The functional interaction of structures that contribute to the act of ____
- A physiologic system that functions to
produce motion of the whole body or of its component parts - The functional interaction of structures that contribute to the act of moving
The movement system is made up of several subsystems necessary for the ____ & ____ of movement
The movement system is made up of several subsystems necessary for the production & regulation of movement
What are the 5 sub-systems of movement?
- Passive
- Active
- Neural
- Support
- Cognitive/Emotional
Support Subsystem
- Includes the ____ status of the integumentary, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive, & digestive systems
- These play an ____ role by not producing motion but providing substrates & metabolic support required to maintain the ____ of the other systems
- Includes the **physiologic **status of the integumentary, circulatory, lymphatic, respiratory, endocrine, urinary/excretory, reproductive, & digestive systems
- These play an indirect role by not producing motion but providing substrates & metabolic support required to maintain the viability of the other systems
What sub-system of movement includes the neurvous system & related to motor function?
Neural Subsytem
What subsystem of movement includes the functional status of the psychological system as it relates to movement?
Cognitive/Emotional Subsystem
Passive subsystem
Includes the the ____ status of the ____ properties of the neuromyofascia & capsuloligmentous, bony & joint-related tissues (e.g., cartilage).
Includes the the structural status of the passive properties of the neuromyofascia & capsuloligmentous, bony & joint-related tissues (e.g., cartilage)
Identify the subsystem of movement
Includes the muscle contractile properties & provides the force/torque requirements for movement.
Active subsystem
Junction between bones that allows slight to essentially no movement
Synarthroses joint
Function of synarthroses joint
Strongly binds & transfer forces between bones
Stabalized by specialized dense connective tissues, usually with high concentration of collagen (structures of the skull, distal tibiofibular joint)
Fibrous
stabilized by flexible fibrocartilage or hyaline cartilage, often mixed with collagen (e.g. symphysis pubis, interbody joints of spine).
Cartilaginous
Articulation that allows moderate to extensive motion
Diarthroses
Elements ALWAYS associated with diarthrodial (synovial) joints (7)
- synovial fluid
- articular cartilage
- joint capsule
- synovial membrane
- ligaments
- blood vessels
- sensory nerves
Elements SOMETIMES associated with diarthrodial (synovial) joints (5)
- intra-articular disc or menisci
- peripheral labrum
- fat pads
- bursa
- synovial plicae
Relative with the degree of mobility occurring along a continuum
Normal mobility
Excessive range of osteokinematic & arthrokinematic motion where there is no protective muscular control
Instability
- Position of maximal congruency
- Most ligaments and parts of the capsule are pulled taught
- Creates natural stability in the joint
- Minimal accessory motion is available here
Close-packed position
- Ligaments and capsule relatively slackened
- Allows increased accessory movements
- Least congruent near midrange
Open-packed position
- Joints with movement primarily in 1 plane of motion is a ____ joint
- Joints that primarily move in more than 1 plane of movement is a ____ joint
- Joints with movement primarily in 1 plane of motion is a stable joint
- Joints that primarily move in more than 1 plane of movement is a mobile joint
