chapter 3 perhaps? Flashcards
what is the science concerned with the study of bones called
osteology
some adults have extra bones w/in the joints (______) of the skull
sutures
what are the extra bones w/in the joints/sutures of the skull called
sutural bones or wormian bones
what are the bones that may develop in tendons in response to stress as the tendons repeatedly move across a joint called
sesamoid bones
what is the largest sesamoid bone
the kneecap of patellae
what is cartilage
a semirigid connective tissue thats weaker than bone but more flexible and resilient
mature cartilage is _____
avascular
what are the three types of cartilage
hyaline cartilage, fibrocartilage, elastic cartilage
the most abundant and weakest type of cartilage, is translucent
hyaline cartilage
the type of cartilage with an extracellular matrix with numerous thick collagen fibers that help resist stretching/compression forces
firbrocartilage
the type of cartilage that contains highly branched elastic fibers
elastic cartilage
what is the process of blood cell formation called
hemopoiesis/hematopoiesis
where is the red bone marrow located
in the spongy bone at the distal ends of long bones
what is the red bone marrow called after it becomes inactive and turned into fatty tissue
yellow bone marrow
where are the select bones where adults have active red marrow that forms blood cells (hematopoiesis)
flat bones of the skull, vertebrae, ribs, sternum (breastbone), bones of the pelvic (ossa coxae), proximal end of the left/right humerus, proximal end of the right/left femur
the hematopoiesis in the active red marrow occurs under the stimulation of ______________ produced by the kidneys
erythropoietin
where is yellow bone marrow (in adults)
the shafts of long bones
long bones
function as levers, bones of the upper/lower extremities
short bones
cube shaped, transfer forces, typically the bones of the wrist and ankle, sesamoid bones are classified as short bones
irregular bones
varied in shape and have many surface projections for muscle attachment or articulation (vertebrae, ossa coxae)
the central shaft of long bones is called the _______
diaphysis
the cylindrical space w/in the diaphysis
medullary cavity
the medullary cavity is lined w a membrane called the _______
endosteum
the expanded, knobby region on the ends of long bones
the epiphysis
the epiphysis is comprised of an outer layer of ______ _____ and an inner layer of ____ ____
compact bone, spongy bone
the epiphysis at a joint surface is covered in a thin layer of hyaline cartilage called the:
articular cartilage
a rough sheath of dense irregular connective tissue that covers the surface of the bone except for areas covered by the articular cartilage
periosteum
the periosteum is responsible for the growth in the _______ of the bone
width
the region between the epiphysis and the diaphysis found in growing children and teens
epiphyseal growth plate
the epiphyseal growth plate is responsible for the growth in ______ of the bone
length
the miotic activity in the epiphyseal growth plate is controlled by
human growth hormone (somatotropin)
the pituitary gland is nestled in the bony “_____ ____” of the ____ ____
“Sella turcica”, sphenoid bone
the only remnant of the piphyseal growth plate in adults is a defined area of compact bone called the
epiphyseal line
stem cells located w/in both the periosteum and endosteum that gives rise to cells that become osteoblasts
osteoprogenitor cells
tendons connect ___ to ___
bones to muscles
ligaments connect ____ to ____
bones to bones
the bone cells that make the bone
osteoblasts
