General Structure and Gross Anatomy of Long Bones Flashcards
-Describe the various parts/regions of a long bone and what occurs at these regions -Name the four cells associated with bone connective tissue and understand the role of these cells -Differentiate compact from spongy bone
True or False:
Irregular bones must be the most common type of bone in our body, because we have so many vertebrae.
False: Long Bone
What are two examples of Long Bones?
Upper Arm (Humorous) and Thigh Bone (Femur)
Diaphysis is Greek for?
Growing Between
True or False:
Within the Epiphysis a hollow cylindrical space called the “medullary cavity”.
False:
Diaphysis
The medullar or marrow cavity contains what?
Yellow Bone Marrow (adipose tissue)
What membrane lines the medullary cavity?
endosteum
The endosteum does what?
Cells associated with the endosteum help to remodel the medullary cavity during bone growth and repair.
True or False:
At each end of a long bone is an expanded, knobby region called the “physis” (Greek for “a growth upon”).
False: Epiphysis
What is the Epiphysis composed of?

The _________ at a joint surface is covered with a thin layer of hyaline cartilage called the “articular cartilage
Epiphysis
What helps to reduce friction and absorb shock in movable joints.
Atricular cartilage
A tough sheath of dense irregular connective tissue, is called the ?
Periosteum
What two tissues cover the Large bone?
Periosteum and Articular Cartilage
Tendon-Muscle attachment to bone is done by what highly vascular tissue?
Periosteum (highly vascular)
True or False:
The Articular Cartilage is responsible for bone width?
False:
Periosteum
