BOOT CAMP Flashcards
Axial vs. Abaxial
Line btw digit 3-4 axial closer to the line
abaxial farther away from line
How do you number digits?
From medial to lateral #1 is sometimes called dew claw
Dorsal vs palmar (manus)
Dorsal vs plantar
Dorsal vs palmar (manus)
Dorsal vs plantar
Proximal vs distal
toward the bod vs farther away from the body
Proximal vs distal
toward the bod vs farther away from the body
Superficial vs deep
superficial and deep layers of muscles
Dorsal Plane
Above the skull, lumbar region
Sagittal Plane
Off to one side of the Median Plane
How to interpret anatomical terms?
meaning: beginning with the prefix, then proceed to the first part of the word and follow through.
Suffix
Modifies the meaning of the word
Roots
the foundation of the word
Prefix
modify the meaning of the root of a word
Terminology
Directional terms
Common prefixes, word roots, etc
What is the Menisci/articular disc and its location?
Structures that are articulation plates that act as cushions between articular surfaces
Articular discs: are found in the temporomandibular (TMJ) joints
Menisci (singular= meniscus) are found in the genual joints
What are the categories and descriptions of ligaments?
Categories: extracapsular (outside of the fibrous part of the joint capsule)
Intracapsular: within the confines of the fibrous part of the joint capsule
Ex: stifle joint has both
Collateral ligament: in both sides of the bone, found mostly in the appendicular synovial joints
What is the Function of ligaments?
stabilize and unite skeletal components
ex: crucial ligaments
Ligament and tendon what is the difference?
Ligament: band of connective tissue that connects two or more bones or cartilages together
Tendon: band or cord of connective tissue that connects muscle to bone
Components of synovial joint
Synovial fluid: protects the joint
Joint capsule: Fibrous layer, synovial layer
Articulation cartilage: closest to bone
Types of Synovial joints
Plane Hinge Ball-and-socket Trochoid Ellipsoid etc.
Synovial joints
Very moveable
Ex: stifle joint (only in the pelvic limb)
In horse front limb is Carpal joint
-Synovial fluid present
-Divide in simple (elbow) or compound (humerus and tibia, phalanges) joint
Fibrocartilaginous joint is and example?
Uniting connective tissue is fibrocartilage
ex: pelvic symphysis, intervertebral discs, mandibular symphysis.
ex: weaker T-10 and L-3 in dogs and rapture.
Fibrocartilaginous joint is and example?
Uniting connective tissue is fibrocartilage
ex: pelvic symphysis, intervertebral discs.
Hayline cartilage joint is? and examples of where it is located?
Uniting connective tissue
Many are temporary and ossify with age
Syndesmosis
between metacarpal and metatarsal is the syndesmosis joint
-Fibours connection: intermetacarpal and intermetatarsal joints
Gomphosis subtype of joint is found where?
Periodontal (right on the tooth) formed by the ligament periodontal ligament
Dental implantations
Incisors, canines, premolars, molars.
Suture type joints are found where?
Skull
Allow growth of the skull
Joints the flat bones of the skull
ex: frontal bones and parietal bones are bilaterally symmetric (SOFT SPOT: joint in middle)
Suture type joints are found where?
Skull
Allow growth of the skull
Joints the flat bones of the skull
Fibrous Joints
little to no movement Subtypes: Sutures Gomphoses And..
What is the Nutrient foramen?
The largest single source is nutrient artery
Where the Nutrient artery passes through
Their position is fairly consistent for each bone
Apophysis is?
Outgrowth of bone
Metaphysis plate is?
the rapid growing, flared segment of a bone located on the diaphyseal side of the epiphyseal plate
Epiphysis plate is?
end/extremity of the bone
Physis plate is?
Where the diaphysis and epiphysis come together
What is Diaphysis plate?
Is the body region of the bone
Intramembranous Ossification
No cartilage model is involved
Bones form directly
Peri-osteal.. On the bone
Endochondral Ossification
Initial formation of cartilage during embryonic development that is reabsorbed and replaced with bone
Primary Centers
Secondary Centers
-Cartilage plate (physis); separate different regions of bone remains btw & separates adjacent centers until bone is mature (humans 25 years of age). Once closed they stop growing
-Continuous cartilage production w/ subsequent resorption and ossification at these plates is what allows a developing bones to ELONGATE
Bone Marrow
Red marrow (hematopoietic marrow): blood cell production Yellow marrow (fatty marrow): fatty content
Spongy Bone a.k.a
Trabecular or cancellous bone
Found in the extremities of long bones, forms internal substance
Compact Bone a.k.a
a.k.a dense or cortical bone
