Straighter line: ANATOMY AND PHYSIOLOGY I quiz
(answered) / BIO201_MH_V3
Compact bone - answers * also called dense or cortical bone
* is a relatively dense connective bone tissue that appears white, smooth, and solid
* it makes up approximately 80% of the total bone mass
Spongy bone - answers * also called cancellous or trabecular bone
* is located internal to compact bone
* appears porous
* makes up approximately 20% of the total bone mass
Interior Cavity of Bone - answers contains a connective tissue that is either red bone marrow or
yellow bone marrow.
3 types of cartilage - answers hyaline cartilage
fibrocartilage
elastic cartilage
Locations of cartilage within the skeletal system - answers hyaline cartilage
* attaches ribs to the sternum (costal cartilage)
* covers the ends of some bones (articular cartilage)
* cartilage within growth plates ( epiphyseal plates)
Locations of cartilage within the skeletal system - answers fibrocartilage
* forms the invertebral discs
* the pubic symphysis ( cartilage between bones of the pelvis)
* cartilage pads of the knee joints (menisci)
Locations of cartilage - answers elastic cartilage
* external ear
* epiglottis of larynx
Hyaline cartilage - answers provides a model for the formation of most of the bones in the
body.
Hyaline cartilage - answers found in adult and juvenile skeleton
Fibrocartilage - answers is a weight-bearing cartilage that withstands compression.
Fibrocartilage - answers found in the adult skeleton
Elastic cartilage - answers is flexible, springy cartilage.
Elastic cartilage - answers are abundant elastic fibers that form weblike mesh.
, Elastic cartilage - answers have chondrocytes in lacunae.
Elastic cartilage - answers have a perichondrium present.
Ligaments - answers anchor bone to bone
Tendons - answers anchor muscle to bone
4 Basic functions of bone - answers support and protection, movement, hemopoiesis, storage of
mineral and energy reserves
Support and Protection - answers Bones provide structural support and serve as a framework for
the entire body. Bones also protect many delicate tissues and organs
from injury and trauma. The rib cage protects the heart and lungs; the cranial bones enclose and
protect the brain; the vertebrae enclose the spinal cord; and the pelvis cradles urinary and
reproductive organs, as well as the terminal end of the gastrointestinal tract.
Movement ( system of levers) - answers Bones serve as attachment sites for skeletal muscles,
other soft tissues, and some organs. Muscles attached to the bones of the skeleton contract and
exert a pull on the skeleton that then functions as a system of levers. The bones of the skeleton
can alter the direction and magnitude of the forces generated by the skeletal muscles. Potential
movements range from powerful contractions needed for running and jumping to delicate and
precise movements required to remove a splinter from the finger.
Hemopoiesis - answers is the process of blood cell production. It occurs in red bone marrow
connective tissue that contains stem cells that form blood cells and platelets.
Storage of Mineral and Energy Reserves - answers Most of the body's reserves of the minerals
calcium and phosphate are stored within and then released from bone. Calcium is an essential
mineral for such body functions as muscle contraction, bloodclotting, and nerve impulse
transmission. Phosphate is required for ATP utilization and is an important component of the
plasma membrane.
When calcium or phosphate is needed by the body: - answers bone connective tissue is broken
down and the minerals are released into the blood.
Potential Energy ( in the form of lipids) - answers is stored in yellow bone marrow in the shafts
of some adult bones.
What two minerals are stored in bone? - answers calcium and phosphorus
Calcium's functions: - answers muscle contraction, bloodclotting, and nerve impulse
transmission
Phosphates functions: - answers required for ATP utilization and component of the plasma
membrane
