Hyoid Bone, Vertebral Column, Sternum, Ribs, Heart Review Flashcards
This is a singular U-shaped or horseshoe shaped bone located in the neck
What is the hyoid bone?
This singular U-shaped, or a horseshoe shaped bone, is located anterior to C4, in the cervical region inferior to the mandible and superior to the thyroid cartilage of the larynx
What is the hyoid bone?
This U-shaped, a horseshoe shaped bone is suspended from the styloid process of the temporal bone by ligaments and muscles
What is the hyoid bone?
This u shaped bone located anterior to C4 supports the tongue, provides attachment sites of the tongue and necks muscles and does not articulate with any other bone in the body
What is the hyoid bone?
This strong flexible group of bones allows us to move anteriorly, posteriorly and laterally and encloses and protects the spinal cord, supports the head and serves as a point of attachment for ribs
What is the vertebral column?
How many bones are there in the adult vertebral column?
26
How many bones are there in the infant vertebral column?
33
The cervical region of the vertebral column has how many bones for infant and adult?
Seven
The thoracic section of the vertebral column has how many bones for infants and adults
12
Lumbar section of the vertebral column has how many bones for infants and adults
5
This region of the vertebral column has five bones for infant, but only one bones for adults
What is the sacrum?
This region of the vertebral column has 4 bones for infants, the only one solid one for adults
What is the coccyx?
Name the five regions of the vertebral column
What is cervical, thoracic, lumbar sacrum, and coccyx?
The bodies of the vertebrae are large, disc- shape portion of the bone. Thus, as we move down the vertebral column, the bodies get bigger so the bodies of the cervical vertebrae, with the exception of C1 are___________ than the bodies of the other sections of the vertebrae
A. Larger
B. Smaller
What’s is b. smaller
How many Foramen’s do all cervical vertebrae have?
What is three
This large Foreman in the middle of the back allows for the passage of the spinal cord
What is the vertebral foremen?
This vertebrae is the first cervical vertebrae, which supports the skull and articulates with the Occipital condyles of the Occipital bone
What is C1 a.k.a. the atlas
This cervical vertebrae has no body and no spinous process, and is described as being a ring of a bone
What is C1 a.k.a. the atlas
This cervical vertebrae is known to have a body, a bifid spinous process and the Dens process
What is C2 a.k.a. the Axis
This tooth or Peg-like Process located in the second cervical vertebrae projects, upwards, and articulates with (the C1 a.k.a. the atlas)
What is the dens process a.k.a. the odontoid process?
This process located on the second cervical vertebrae allows the head to pivot and permits, the side to side movement of the head when you move your head to say no
What is the dens process a.k.a. the odontoid process?
These processes of the cervical vertebrae, each have a bifid spinous process, but no special name
What is C3 - C6
This cervical region is the most prominent of the cervical vertebrae, because it possesses a large, non-bifid spinous process
What is C7 a.k.a. the cervical prominens?
This portion of the vertebrae is larger in size than the cervical vertebrae and the spinous process projects inferiorly, with all ribs, articulating posteriorly with this part of the vertebrae
What is the thoracic region T1 - T12
This region of the vertebrae is known to be the largest and the strongest, and it’s equipped for full weight bearing, and the various projections are known to be “short and thick”
What is the lumbar region L1 through L5?
This vertebrae is located in the posterior portion of the pelvic cavity, medial to the two hip bones, and serves as a strong foundation for the pelvic girdle where lower extremities attach to the trunk of the body
What is the sacral region (S1) (S1 - S5 in infants)
This triangular bone formed by the union a five vertebrae is located on the lower portion of vertebrae and serves as a strong foundation for the pelvic girdle…
What is the sacral region S1 (in infants S1 through S5)
Formed by the fusion of four vertebrae, This region is known to as the tailbone, and is the most inferior portion of the vertebral column.
What is the
Coccygeal region C 01 (and infants C 01 to C 04)
These pieces of fibrous cartilage are located between the bodies of each vertebrae from C2 to the sacrum, and act a shock absorbers
What are Intervertebral Discs?
Informally known as the breast bone this singular bone is described as a flat sword or dagger-shaped bone, located in the anterior midline of the chest
What is the sternum?
This bone informally known as the breast bone articulates with the first right and left ribs and the clavicle , (a.k.a. collarbone)
What is this sternum
Name the three parts of the sternum
The manubrium, the body, a.k.a. gladIolus and this xiphoid Process, a.k.a. the ensiform process
This superior triangle portion of the sternum is where the clavicle in the first rib articulates
What is the manubrium
This part at the sternum is the middle and largest part of the sternum
What is the body a.k.a. gladiolus
This part of the sternum forms, the most inferior part of the sternum, and it’s a smaller portion of the sternum
What is the xiphoid process a.k.a. Ensiform process
This notch is located in the sternum, and is a depression in the medial superior portion of the manubrium
What is the jugular notch a.k.a. suprasternal notch?
Is notch is located on each side of the jugular notch and articulates with the medial end of the clavicle, forming the sternoclavicular articulation
What are the clavicular notches?
This part of the sternum is where the manubrium meets the body and where the second rib articulates
What is the sternal angle or the angle of Louis?
How many ribs are there in the human body?
There are 24 ribs (not 12 pair) 24 ribs…
These bones protect the vital organs of the thorax
What are ribs?
These ribs are the first seven pairs, and attached directly to the sternum by there on coastal cartilage
What are true ribs?
These ribs costal cartilage does not attach directly to the sternum and instead attached to each other, and then attach to the cartilage of the seventh rib (indirectly to the sternum)
What are false ribs? (Ribs 8 -10)
These special kind of false ribs do not attached to the sternum at all, and the only point of attachment is the thoracic vertebrae
What are floating ribs? (Rib 11-12)
