Unit 1 Flashcards
Median Sagittal
Vertical plane that passes through the midline, dividing the body left and right
Sagittal/ Parasagittal
Vertical plane that is parallel to the median sagittal
Coronal
Plane that divides the body from front and back
Transverse
Horizontal plane that divides the body from upper and lower, across the body
Longitudinal
Any plane that is perpendicular to the transverse plane, on arms and legs
Superior/ Cranial
Top, closer to the head
Inferior/ Caudal
Bottom, closer to the feet
Anterior/ Ventral
In front of another
Posterior/ Dorsal
Behind another
Medial
middle, closer to the center of the body/ Median Sagittal plane
Lateral
to the side, further away from the middle/ Median Sagittal plane
Proximal
closer to the root/ attachment of the limb
Distal
further from the root/ attachment of the limb
Superficial
further away from the inside of the body, closer to the skin
Deep
closer the the center of the body, deeper inside
Palmar
the surface of the hand with finger tips
Plantar
the surface of the foot with toe tips (sole)
dorsal
the surface of the the foot or hand opposite of palmar and planter
Mesial
the teeth that are closer to the front of the mouth, towards the anterior midline
Distal
the teeth that are towards the back of the mouth, away from the anterior midline
Lingual
towards the tongue
Labial
towards the lips
Buccal
towards the cheeks
Occlusal
the top part of the teeth, the surface that comes into contact with the teeth in the other jaw
Flexion
movement that decreases the angle
Extension
movement that increases the angle
Abduction
moving away from the median sagittal plane
Adduction
moving towards the median sagittal plane
Rotation
moving around a central axis of body
Pronation
motion of the arms when the thumb points down, palm points posteriorly
Supination
motion of making the hand in the anatomical position
Eversion
the foot faces outward away from the midline, toes points outwards
Inversion
the foot faces inwards towards the midline, toes points inwards
Plantarflexion
toes points down, ballet pointed toes
Dorsiflexion
toes points up
Circumduction
movement of limb in a circular or cone shape, ex: arm circles
Opposition
movement of the thumb to touch each finger tips
Compact Bone
type of bone tissue that is the outer most layer
Cancellous (Spongy) Bone
type of bone tissue that is located internal to the compact bone
Trabeculae
tissue making bands and rods within the bone, the space within is filled with red marrow, producing red blood cell (looks like webs)
Periosteum
a collective tissue that surrounds the bone that the tendon of muscles are attach to
Osteons
cylindrical vasular tunnels formed by osteoclast-rich tissues that is responsible for the strength of the bone
Haversion Canal
at the center of each osteon that runs longitudinally, carrying nerves and blood vessels
Nutrient Artery
supplies large bones (arms, forearms, thighs, legs) with nutrients, enters the bone through the nutrient foramen
Diaphysis
shaft of the bone, made up for compact bone that surrounds the Medullary (marrow) Cavity
Medullary (marrow) Cavity
inside the diaphysis, filled with fatty yellow marrow
Epiphysis
each end of the bone; some bones has multiple epiphysis, long bones of fingers and toes only have 1
Metaphysis
made of trabeculae that separates the epiphysis and diaphysis
Epiphyseal (Growth) plate
plate between the epiphysis and metaphysis
Ossification
the process which the epiphyseal plate is fused together, growth in that bone stops
Axial Skeleton
the part of the skeleton that contains the skull, vertebral column, sacrum, coccyx, and thoracic cage; mainly the middle part of the body
Appendicular Skeleton
the part of the skeleton that contains the pectoral girdle, upper and lower limb bones, and pelvic girdle; anything that isn’t the axial skeleton
Fibrous Joints
one type of joint that has very little mobility, joined by fibrous connective tissues
Suture
one type of fibrous joint, the lines that we see and is found in the skull
Syndesmosis
one type of fibrous joint, that are connect by short collagen ligament, found in the long bone of the limbs connecting the two bones and at the end
Gomphosis
one type of fibrous joint, connects that teeth and the bone of the face
Cartilaginous Joints
one type of joint that are entire joined by cartilage
Synchondrosis
one type of cartilaginous joints that are connected by the hyaline cartilage that is found between the metaphysis and epiphysis of a growing bone
Symphysis
one type of cartilaginous joints that are connected by a pad of fibrocartilage that doesn’t have much movement, they are found in the pubic symphysis of the pelvis and the interverebral discs
Synovial Joints
one type of of joint that is extremely mobile and has a joint cavity, unlike the other two joint
Articular Cartilage
the surface of the adjacent bone that are covered with a layer of hyaline cartilage
Joint Capsule
the articular capsule and the spaces in between them that are enclosed
Capsular Ligament
the external part of the capsule that is composed of elastic fibers stretching from one bone to another
Synovial Membrane
the internal part of the capsule that secretes a lubricating synovial fluid
Bursa
lubricating device that cushions a tendon as it crosses over the capsular ligament
Articular Disc
attached to the fibrous joint capsule, in between the two articular surfaces
