Anatomy skeletal system
the shaft of a long bone is called a
diaphysis
what is the bone of the brachium
humerous
intramembranous ossification results in the formation or which bone
mandible
bone cell capable of dissolving the bony matrix
osteoclasts
which of the following is essential for normal bone growth
calcium, sex hormones, vitamin D3
what is the main difference between spongy bone and compact bone
compact bones contain osteons, and spongy bones contain trabeculae
what is responsible for the production of new bone
osteoblasts
areas of solid bone where two skull bones join
sutures
the shaft of a long bone is called the
diaphysis
what is a freely moveable joint
diarthrosis
the order of endochondral ossification
-calcification of matrix surrounding chondrocytes -cells from the perichondrium differentiate into osteoblasts -formation of the primary ossification center -osteoclasts break down the spongy bone to create marrow cavity -formation of the secondary ossification centers
what is a slightly moveable joint
amphiarthrosis
While observing bone tissue, you notice that osteoblast activity exceeds osteoclast activity. Which of the following events are you observing?
bone growth
the smooth, rounded, or oval articular process of a bone is termed a
condyle
the hormone calcitonin functions to
depress calcium levels in body fluids
soft spots that are made of fibrous connective tissue, which will eventually fuse to form the sutures of the skull
fontanelles
a round opening through the bone that acts as a passageway for blood vessels or nerves is anatomically referred to as a
foramen
the head of the humerous articulates with what on the scapula
glenoid cavity
the connective tissue covering the outer surface of a bone is the
periosteum
as you stand on the tip of your toes to reach the top shelf of the cabinet, which joint movement are you performing
plantar flexion
what is the lateral bone of the forearm
radius
what is are the functions of the skeletal system
support, movement, and storage
What is an immovable joint?
synarthrosis
