Articulations Flashcards
What are the functional classification of articulations: Based on movement
Synarthrosis
amphiarthrosis
diarthrosis
What type of functional classification of articulations: Based on movement is this?
________:are immobile joints like the sutures found between the bones of
the cranium.
Synarthrosis
What type of functional classification of articulations: Based on movement is this?
_______:are joints that allow a slight amount of movement like the
intervertebral discs made of fibrocartilage found between the bodies of adjacent vertebrae.
Amphiarthrosis
What type of functional classification of articulations: Based on movement is this?
_______:are freely movable articulations and include many familiar
examples such as the elbow, shoulder, and knee
Diarthrosis
What are the structural classification of articulations?
Fibrous joints
Cartiliginous joints
Synovial joints
What type of structural classification of articulations is this?_______- held together by dense fibrous CT
• _______- fibrous synarthrosis
o ex: cranial sutures
• ______- ligament connects bones
o ex: distal radio-ulnar joint
• ________- ligament holds teeth to dental alveoli
• _______- two bones fuse
o ex: epiphyseal lines, coxal bones (ilium, ischium and pubis fuse), frontal bone
(left and right fuse)
- ***Fibrous joints
- Suture
- Syndesmosis
- Gomphosis
- Synostosis
What type of structural classification of articulations is this?
______- held together by cartilage
• _______- cartilaginous synarthroses ex: sternocostal joints
• _________- amphiarthroses of fibrocartilage ex: pubic symphysis
- ***Cartiliginous joints
- Synchondrosis
- Symphysis
What type of structural classification of articulations is this?
______-capsule of fibrous CT surrounding a fluid filled cavity ex: all diarthroses
Synovial Joint
Types of movements:
16 types
Flexion Extension Dorsiflexion Plantar flexion abduction Rotation Protation Supination Elevation Depression Circumduction Inversion Lateral flexion protraction Retraction
Types of movements:
_______moves away from anatomical position through sagittal plane
Flexion
Types of movements:
______:opposite of flexion returns to anatomical position
Extension
Types of movements::
______:raises the toes superiorly
Dorsiflexion
Types of movements:
______:pushes the toes inferiorly
Plantar Flexion
Types of movements:
________:move away from the longitudinal axis in frontal plane
_____opposite
of abduction returns to anatomical position
Abduction
Adduction
Types of movements:
_______-turn around long axis of bone. The head is along the midline so we can
rotate the head left or right. The limbs can rotate lateral away from the midline or medial
toward the midline.
Rotation
Types of movements:
_______-medial rotation of forearm
Pronation
Types of movements:
_____- opposite of pronation returns to anatomical position
Supination
Types of movements
______-raise superior ex: closing the jaw
Elevation
Types of movements
______- lower inferior, opposite of elevation ex: opening the jaw
Depression
_______ is a combination of flexion, extension, adduction and abduction.
Example: hand moving in a circle, eyes
Circumduction
_____ moving the foot (pedal) laterally
inversion
____ moving foot (pedal) medially.
eversion
___ moving your body laterally.
EX: moving vertebral laterally, or moving your head side to side.
Lateral flexion
______ is movement of a body part in the anterior direction, i.e. being drawn forwards
Ex; moving (scapula) shoulder blades inward.
Protraction
______is movement of the body part in the posterior direction.
Ex; Moving shoulder blades ( scapula) outward.
Retraction
Types of synovial Joints:
Piviot joint Hinge joint Saddle joint Plane joint Condyloid joint Ball- and- socket joint
What Types of synovial Joints is this?
______- allows rotation only
• ex: Atlantoaxial joint between C1 and C2, Proximal radioulnar joint
Pivot Joint
What Types of synovial Joints is this?
_____- allows angular motion of flexion/extension
• ex: Elbow or Knee
Hinge Joint
What Types of synovial Joints is this?
_______- surface concave on one axis convex on other enables flexion and
abduction
• ex: Carpalmetacarpal joint between the trapezium and the first metacarpal
Saddle Joint
What Types of synovial Joints is this?
________- allows a small amount of sliding
• ex: Intercarpal joint between the scaphoid and trapezium, Clavicle and sternum
Plane Joint
What Types of synovial Joints is this?
______-oval face in a depression allows flexion and abduction
• ex: Metacarpalphalangeal joints
Condyloid joint
What Types of synovial Joints is this?
_______- flexion, abduction, rotation, and circumduction.
• Ex: Shoulder and hip
BAll- and -Socket joint
