Module 2 - Overview Flashcards
3 bones that make up the pelvis
Ilium, ishium, pubis
Functions of the skeletal system
- Supports the body
- protect vital organs
- movement
- produce blood cells
- stores fats and minerals
5 classifications of bones
Short, long, irregular, sesamoid, flat
Cylindrical shaft of a long bone
Diaphysis
Two ends of a long bone
Epiphysis
Where the epiphysis and diaphysis meet
Metaphysis (epiphyseal line)
Centre cavity of diaphysis
Medullary cavity
Fills the medullary cavity
Yellow bone marrow
Connective tissue sheath around diaphysis, considered bone’s life support system
Periosteum
Vascular channels that run longitudinally in compact bone
Haversian canals
Vascular channels that run horizontally in compact bone
Volkmann’s canals
Bone forming cells
Osteoblasts
Bone destroying cells
Osteoclasts
Mature osteoblasts
Osteocytes
Process of bone development where pre-existing connective tissue is replaced with osseous tissue
Ossification
Formation of bone from membranous tissue
Intramembranous
Formation of bone from cartilage
Intracartilaginous
Skull, vertebral column, sternum, ribs, sacrum, coccyx - located in the ______ skeleton
Axial
Shoulder girdle, pelvic girdle, upper and lower limbs located in the _____ skeleton
Appendicular
Articulation and arthrosis are terms synonymous with _______
Joint
Fibrous joint where movement is absent or limited
Synarthroses
Cartilaginous joints that are slightly moveable
Amphiarthroses
Synovial joints that are freely moveable
Diarthroses
6 types of synovial joints
Hinge, pivot, ellipsoidal, gliding, saddle, ball and socket
These 2 synovial joints are monoaxial joints
Hinge and pivot
These 2 synovial joints are biaxial
Ellipsoidal and saddle
These 2 synovial joints are multiaxial
Gliding and ball and socket
Functions of the muscular system
- mobility (motion and locomotion)
- heat generation
- posture maintenance
- motility (smooth muscles)
Connective tissue that wraps around muscle groups
Deep fascia
Connective tissue that wraps around entire muscle
Epimysium
Connective tissue that wraps around fasciculi
Perimysium
Connective tissue that wraps around muscle fibres (or muscle cells)
Endomysium
Structure containing myofilaments
Myofibril
Group of muscle fibres (or muscle cells)
Fascicle
Arrange from smallest to largest: muscle fibre, myofilament, muscle, fascicle, myofibril
SMALLEST
- myofilament
- myofibril
- muscle fibre
- fascicle
- muscle
LARGEST
A broad flat tendon
Aponeurosis
Retaining bands for tendons
Retinacula
The cell membrane of a muscle cell
Sarcolemma
The cytoplasm of a muscle cell
Sarcoplasm
Fluid-filled system of cavities that contain calcium ions for muscular contraction
Sarcoplasmic reticulum
Thin myofilament
Actin
Thick myofilament
Myosin
____ and ____ are proteins that cover the binding sites on a strand of actin
Tropomyosin and troponin
Sarcomeres are present in segments along ________
Myofibrils
A muscle’s contractile unit
Sarcomere
Ends of a sarcomere
Z-line
__ Band: Centre of sarcomere ( myosin only)
H Band
__ Band: actin and myosin overlapping
A-Band (think A for and)
__ Band : actin only
I-Band
Describes a muscle ability to respond to a stimulus
Excitability
Describes a muscle’s ability to shorten and lengthen
contractility and extensibility
Describes a muscle’s ability to return to normal shape after movement
Elasticity
This types of response says muscle fibres will contract to their fullest extent or not at all
All-or-nothing response
The principle neurotransmitter involved in muscle contraction
Acetylcholine
A folded section of sarcolemma @ neuromuscular junction
Motor end plate
The nerve impulse is carried into the muscle cell via ________
T-tubules
A type of skeletal muscle fibres known as red muscle. They are fatigue resistant, have a good blood supply and produce ATP fast enough to meet needs
Slow twitch muscle fibres
A type of skeletal muscle fibres known as white muscle. They contain little myoglobin, and fatigue easily
Fast twitch muscle fibres
A type of skeletal muscle fibres known as pink muscle.
Intermediate muscle fibres
Muscle crossing one joint
Uniarticular
Muscle crossing two joints
Biarticular
Muscle crossing more than 2 joints
Multiarticular
6 muscle fibre arrangements
Parallel, convergent, fusiform, circular, unipennate, bipennate
Honest and open sharing of emotions, as well as insights and ideas
Self-disclosure
The non-disclosure of privileged information
Confidentiality
A set of guiding moral principles that governs the individual’s course of action
Code of ethics
Occurs when the client transfers feelings, thoughts, and behaviour related to a significant person in their early life onto the therapist
Transference
Occurs when the therapist brings in their own unresolved issues or personal needs into the therapeutic relationship
Countertransference
A profession’s working parameters
Scope of practice
