Gross/Micro Bone Anatomy
What type of bone is porous and found at the end of long bones?
Spongy Bone
True or false: There's 4 sets of floating ribs
False.
What is: an incomplete break in a bone where the bone splits, cracks, or breaks but does not break completely through, shift, or become displaced
A fissure fracture
What bone disorder matches this description: a common, "silent" bone disease characterized by decreased bone mass and density, which leads to weak, fragile bones that are highly susceptible to fractures. It occurs when the body fails to form enough new bone, or when too much old bone is reabsorbed by the body, altering the structural integrity of the skeleton
Osteoporosis
What is this an example of: Examples include the elbow, knee, and finger joints, this type of synovial joint allows for movement in only one plane, similar to a door.
Hinge Joint
What canal runs through the center of an osteon and contains blood vessels and nerves?
Central (Haversian) Canal
True or false: The cranial bone thats shaped like a "bat" is the palatine bone.
False
What is: a specific type of broken bone where the break runs straight across the bone, perpendicular (angle) to the long axis. These are typically clean, horizontal breaks that go all the way through the bone, often classified as complete fractures
Transverse Fracture
What bone disorders match this description: a disorder that causes the softening and weakening of bones in children, typically resulting from an extreme, prolonged deficiency of vitamin D, calcium, or phosphate
Rickets
What is this an example of: Connecting bones to other bones, these strong, fibrous connective tissues stabilize joints and restrict abnormal movement.
ligaments
What is the lining around a bone called?
Periosteum
True or false: provides structural support, protects vital organs, and enables movement by acting as levers for muscles relates to the functions of the skeletal system.
True
What is: a type of complete bone break that occurs when a long bone is subjected to a severe twisting force or torque
Spiral Fracture
What is this: also known as osteophytes, occur
when the body grows small projections on the edges
of bones
Bone spurs
what is this an example of: Found in the shoulder and hip, this type of synovial joint offers the greatest range of motion, allowing for movement in multiple axes.
Ball and socket joint
What bone cell breaks down bone tissue?
Osteoclasts
True or false: osteoblasts break down bones, osteoclasts are mature bones, and osteocytes build bones.
False:
Osteoblasts - build
Osteoclasts - break down
Osteocytes - mature bone cells
what is: a break that occurs at a diagonal or slanted angle across the shaft of a bone
oblique fracture
What bone disorder matches this description: a condition where bone tissue becomes fibrous, making bones weaker
Fibrous dysplasia
what is this an example of: Immovable or fixed joints, such as those found between the plates of the cranium, are classified as this type.
Fibrous Joints (or Synarthroses)
What small channels allow the osteocytes communicate and exchange nutrients?
Caniliculi
True or false: the largest foot bones are cuboid and navicular
False: calcaneus and talus
what is: an incomplete break in a bone where the bone bends and cracks rather than breaking completely into separate pieces
What bone disorder is this: common cause of heel pain, inflammation of the plantar fascia,walking can be painful
Plantar fasciitis
what is this an example of: This specifically shaped joint, found at the base of the thumb, allows for biaxial movement (flexion/extension and abduction/adduction).
Saddle Joint
