Example Question #41 : Identifying Bones Of The Trunk And Core
Which of the following portions of the vertebral column represent primary curvature?
Cervical and lumbar
Thoracic and sacral
Thoracic and lumbar
Lumbar and sacral
Thoracic and cervical
Thoracic and sacral
Primary curvature is found in newborns, whereas secondary curvature develops over time. The thoracic and sacral portions of the vertebral column are convex, giving babies a more hunched posture.
Example Question #42 : Identifying Bones Of The Trunk And Core
Which bone lacks a spinous process and receives the occipital condyles?
T2
T1
Atlas
L1
Axis
Atlas
Atlas is another term for C1. Its superior articular facets receive the condyles of the occipital bone in the skull, which allows the neck to move backwards and forwards. The axis, or C2, has a superiorly projecting dens that distinguishes it from the atlas.
Example Question #43 : Identifying Bones Of The Trunk And Core
Muscles around the __________ bone attaches to the mandible and larynx and contributes to swallowing.
hyoid
thyroid
C3
atlas
axis
hyoid
The hyoid bone acts as an attachment point for many muscles in the neck. When swallowing, the larynx is elevated and the epiglottis is removed from the glottis, allowing matter into the esophagus.
Example Question #44 : Identifying Bones Of The Trunk And Core
Which of the following describes the normal sagittal curvatures of the adult spinal column?
Cervical - lordotic; thoracic - kyphotic; lumbar - straight; sacrococcygeal - kyphotic
Cervical - kyphotic; thoracic - kyphotic; lumbar - lordotic; sacrococcygeal - kyphotic
Cervical - lordotic; thoracic - kyphotic; lumbar - lordotic; sacrococcygeal - kyphotic
Cervical - straight; thoracic - kyphotic; lumbar - lordotic; sacrococcygeal - kyphotic
Cervical - lordotic; thoracic - kyphotic; lumbar - lordotic; sacrococcygeal - kyphotic
The spine has three natural curves when viewed from a saggital/lateral view. The "c-shaped" curvature (seen in the neck and lower back) is called lordosis, while the "reverse c-shape" (seen in the thoracic spine) is called kyphosis. Now that we have reviewed these terms, the follow describes normal curvature of the spine: Cervical - lordotic; thoracic - kyphotic; lumbar - lordotic; sacrococcygeal - kyphotic.
Example Question #45 : Identifying Bones Of The Trunk And Core
Which of these vertebrae has a longer spinous process than the others?
C1
L1
C5
T5
T5
A spinous process is a bony projection off the posterior aspect of the vertebrae. The spinous process functions as a site of attachment for muscles and ligaments. The spinous processes of the thoracic spine are much longer compared to the cervical and lumbar vertebrae. Lumbar vertebrae have thicker, shorter, and more robust spinous processes, while cervical have short spinous processes.
Example Question #253 : Gross Anatomy
Which of the following bones has mammillary processes?
T1
L2
Sacrum
C5
L2
The lumbar vertebrae are the largest and most robust of the vertebrae as they need to support more weight than the rest of the spine. They are the only vertebrae that possess mammillary processes. The mammillary process is the site of attachment of the multifidus muscle, a muscle that runs the length of the spine to provide spinal support.
Example Question #46 : Identifying Bones Of The Trunk And Core
The vertebrae are an example of which type of bone?
long Bone
sutural Bone
flat Bone
irregular Bone
short Bone
irregular Bone
The vertebrae are irregular bones. These bones have a pointed, obscure shape that does not fit into any other standard category. Other irregular bones include the hyoid and sacrum. An example of a long bone is the femur. An example of a short bone are the carpal bones in the hands and feet. An example of a flat bone are the ribs. An example of a sutural bone is the bones of the skull.
Example Question #47 : Identifying Bones Of The Trunk And Core
How many cervical vertebra are there?
There are 7 cervical vertebra. The thoracic region has 12, and the lumbar has 5. You can remember this by thinking of the regions as time of day. The morning (head/neck region) is at 7am, the middle of the day (thoracic) is at 12, and the end of the day (lumbar) is at 5pm.
