Lecture Exam #2 Flashcards
- provides flexibility, - provides rigidity (in a bone)
collagen, calcium salts
Bone features for muscle attachment
Protuberance, tuberosity, process, trochanter
Motion that increases joint angle between two bones
Extension
Motion that increases a joints angle away from midline of body
Abduction
Primarily made of cartilage
Lateral meniscus
Parietal bones are example of
Flat bone
Cells that eventually turn into osteocytes
Osteoblasts
Which two ligaments CROSS each other within the joint
ACL/PCL (CRUCIATE)
Chambers containing osteocytes
Lacunae
Responsible for MAINTAINING adult bone density
Osteocytes
Shake your head yes, skull is
Flexing forward on atlas
Structures part of ethmoid bone
Cribriform plate, perpendicular plate, nasal conchae, pterygoid plates/processes
Explain why female pelvis is wider than male pelvis
Wider female pelvis provides larger passage for child birth, narrower male pelvis acts like suspension bridge to support greater male weight
Purpose of ischiofemoral ligament
Helps stabilize coxal joint
What bone is external acoustic meatus found in
Temporal
Gene critical for sex determination (production of androgens)
Sry gene
Condition where a person with XY sex chromosomes fails to develop normal secondary sexual characteristics seen in males
Androgen insensitivity
Allows sensory nerves to exit bone, feeling in skin on forehead
Supraobital foramen
Femur is constructed to withstand high levels of
Compression, tension, bending
Functional unit of compact bone, made up of concentric rings of compact bone (surround central canal)
Osteon
What type of joint is the knee
Monoaxial
Knee ligament LEAST likely to be torn in non contact sports injury
LCL
Transfers weight from tibia onto foot
Talus
Process of tibia providing support for ankle
Medial malleolus
costae, femur, scapula, radius, phalanges (which is not part of appendicular skeleton)
Costae
Suture that forms articulation of frontal and parietal bones
Coronal suture
Calcitonin - by - the activity of -
Lowers blood calcium, suppressing, osteoclasts
Bone is fractures, breaks into multiple pieces
Comminuted fracture
Provides structural reinforcement, help make lateral edges of orbit stronger
Zygomatic arch
Mandible articulates with temporal bone at the
Mandibular fossa
Important for cleaning and moistening inhaled air
Nasal conchae
Elbow, biceps brachii, and forearm are examples of
3rd class lever
Vertebra that have transverse foramina are the
Cervical vertebrae
The - and - are missing on the C1 vertebrae (AXIS)
Body, spinous process
Which bone contains foramen magnum
Occipital
Purpose of glenohumeral and acetabular labrums
Help stabilize respective joints
Glenoid cavity is found on the
Scapula
Greater and lesser tubercles found on the
Humerus
Growth pattern by which bones grow thicker is - and is done primarily by -
Appositional bone growth, osteoblasts
What ligaments combine with others to create joint clause around hip joint
Illiofemoral, ischiofemoral, pubofemoral
During development of long bones, secondary ossification center occurs in the
Epiphysis
Bone in your hand that trachea to your index finger is the
Metacarpal II
Arch is an important feature of the foot that
Provides shock absorption while walking, distributes weight of body over entire foot
Which cranial bones contains a large sinus
Maxillary, sphenoid, ethmoid, frontal
What makes bone flexible
Collagen
What provides bone stability and rigidness
Calcium
Bone features for muscle attachment
Trochanter, tubercle, process, tuberosity, condyle
