The Skeletal System contains how many bones? What are the two major divisions of the skeletal? 206; axial and appendicular
What division of the skeleton forms the axis of the body? Axial skeleton
The axial skeleton consists of what body parts? Skull, Vertebral column and rib cage
The appendicular skeleton consists of what body parts? Supports the appendages (limbs); consists of the bones of the arms and legs (upper & lower extremities) shoulder and pelvic girdles
Name the various types of bones... Short bones, Flat bones, Irregular bones, Sesamoid bones, Wormian bones
This type of bone is a sutural bone found in between sutures and varies in number. Wormian Bones
This type of bone is shaped like a sesame seed and varies in number and not always completely ossified. Sesamoid bones
Name this type of bone that protects tendons from excessive wear & tear. Sesamoid bones
The patella and pisiform are examples of this bone. Sesamoid bones
This type of bone comes in a variety of complex shapes and made of varying amounts of spongy and compact bone. Irregular bones
The vertebrae and facial bones are examples of this type of bone. Irregular bones
Name this type of bone: Made of two almost parallel plates of combact bone around spongy bone. Flat bones
The sternum, ribs, scapula, hip bones and cranial bones are examples of this type of bone Flat bones
This bone is somewhat cube-shaped and its length is equal to its width and it is made mostly of spongy bone covered by a thick layer of compact bone. Short bones
Bones of the wrist except for the pisifrom which is a sesamoid bone and ankles except for the calcaneus which is irregular are examples of this bone. Short bones
These are structural features adapted for specific functions. Bone Markings
These sites allow the passage of short tissue (nerves, blood vessels, ligaments, and tendons) or formation of joints: fissure, foramen, fossa, sulcus, meatus Depressions and Openings
These projections or outgrowths on bone that form joints or attachment points for CT, such as ligaments and tendons Processes
Condlyes, Facets and Heads are processes that form _. Joints
Name the processes that form attachment points for CT. Crest, epicondyle, line, spinous process, trochanter, tubercle, tuberosity
In the skull, how many cranial bones are there? Eight.
In the Skull, how many facial bones are there? Fourteen
Name the 8 Cranial bones frontal, 2 parietal, 2 temporal, occipital and sphenoid and ethmoid
Name the 14 facial bones mandible, 2 maxilla, 2 nasal, 2 lacrimal, 2 zygomatic, 2 palantine, 2 inferior nasal conchae, and the vomer. Only the mandible is movable.
What is the only movable bone in the face? Mandible
These are immovable joints in an adult found only between cranial bones and holds the skull bones together. Sutures
T or F: Immovable joints between cranial bones found in babies are called Sutures. False- Sutures are found in adults. Fontanelles or "soft spots" are found on babies.
What is the name for paired cavities in certain cranial and facial bones near the nasal cavity; serve as echo chambers for sound in speaking & singing Paranasal sinuses
These serve as echo chambers for sound in speaking & singing Paranasal sinuses
Only bone in body that does not articulate with any other bone is called the _ bone. Hyoid
Where is the hyoid located? In front of the neck between the mandible and larynx, suspended from the temporal bones by ligaments and muscles
What is the function of the hyoid bone? It supports tongue and provides attachment for muscles of tongue, neck and pharynx.
What is the Vertebral Column (Spinal Column, Backbone)? Made up of individual bones called vertebrae; vertebral canal houses the spinal cord and protects it.
What are neck bones in the vertebral column known as? How many 7are there? Cervical;
What is C1? What is it's proper name? A ring of bone without a body or spinous process; atlas
What are the three abnormalities of the Spinal Column? Scoliosis, Kyphosis, Lordosis
This abnormality has an exaggerated thoracic curve or "hunchback" Kyphosis
This abnormality has an exaggerated lumbar curve or "swayback" Lordosis
The abnormal lateral curvature of the spine resulting from one leg being longer than the other, displacing the rib cage to one side Scoliosis
What is a Thoracic Cage? A bony enclosure formed by the sternum, costal cartilages, ribs and bodies by thoracic vertebrae.
What is the function of a Thoracic Cage?
