Suffolk test 3 Flashcards
Skull Hyoid Vertebrae Ribs Sternum Ear ossicles Are part of
Axial skeleton
Support Movement Storage of minerals calcium and phosphate Blood cell production Energy storage
Functions if bone
Upper and lower limbs
Hip
Shoulder
All are part of
Appendicular skeleton
Bones that are longer than they are wide
Long bones
Sesamoid bones are
Cube shaped bones of the wrist and ankle
Sesamoid bones are formed within
Tendons - patella
Flat bones ex
Sternum and most skull bones
Irregular bone examples
Vertebrae
Hip bones
Type of cartilage over joint surfaces that act as friction reducers and shock absorber
Articular cartilage
Red bone marrow is found in
Spongy bone
Medullary cavity
Marrow cavity
Compact bone is arranged in units called
Osteons or haversion systems
Contains blood vessels, lymphatic vessels, nerves & osteocytes along w the calcified matrix
Osteons
Muscles only pull never
Push
As muscles shorten the insertion moves toward the
Origin
Whatever a muscle group does another muscle group
Undoes
Provides the major force for producing a specific movement
Prime movers
Opposes or reverses a particular movement
Adds force to a movement
Reduces undesirable or unnecessary movement
Adds force to a movement
Reduces undesirable or unnecessary movement
Synergists
Synergists that immobilize a bone or muscles origin
Fixators
Factors when naming skeletal muscles
Location
Shape
Size
Direction of fibers
Rectus fibers run
Straight
Oblique fibers run
At angles
Muscle called orbicularis encircles what
The mouth
Convergent fascicles can be found where
Pectoralis major
Chest
Multipennate fascicles can be found
Deltoid
Shoulder
Parallel fascicles can be found
Sartorious
Long muscle inner thigh
Fusiform fascicles can be found
Biceps brachii
Unipennate fascicles are found
Extensor digitorum longus
Lower limb
Bipennate fascicles found
Rectus femoris
Thigh
A point of contact between two or more bones between cartilage and bones or between teeth and bones
Joint
Articulation or arthrosis
The scientific study of joints is called
Arthrology
Area inbetween two articulating bones
Synovial cavity
Contains synovial fluid
Joints hold bones together but permits
Movement
Study of motion
Kinesiology
Structurally joints are classified as
Fibrous
Cartilaginous
Synovial
Functional classification of joints
Synarthosis
Immovable
Amphiarthrosis
Slightly movable
Diarthrosis
Freely moveable
Type of joint that
lacks a synovial cavity
Holds bones together with fibrous connective tissue
Little or no movement
Fibrous joints
3 structural types of fibrous joints
Sutures
Syndesmosis
Gomphosis
What types of joints are found in the skull
Fibrous
Found in the sutures
Syndesmoses is what type of joint and located where
Fibrous joint
Between tibia and fibula
What structural joint is found between tooth and alveolar process
Gomphosis
If dense fibrous connective tissue are fused in adults it’s called
Synostosis
Interosseous membrane is made of what type of joint
Fibrous joint
Lacks synovial cavity
Allows little or no movement
Bones tightly connected by fibrocartilage or hyaline cartilage
Cartilaginous joints
2 types of cartilaginous joints
Synchondroses
Symphyses
Synchondrosis connecting material is
Hyaline cartilage
Synchondrosis is found
Between ribs and sternum
Epiphyseal plates
Symphysis connecting material is
Fibrocartilage
Symphases can be found
Inverterbral disc and
Pubic symphysis
Synovial cavity is diarthrosis meaning
Freely moveable
This cartilage found in synovial joints reduces friction and absorbs shock
Articular cartilage
Inner synovial membrane contains
Synovial fluid
Outer fibrous capsule of the articular capsule may contain
Ligaments
