Which type of vertebrae contains passageways for blood vessels?

Which type of vertebrae contains passageways for blood vessels?

vertebral column

Which type of vertebrae have transverse foramen which are passageways for arteries leading to the brain?

The transverse processes of the cervical vertebrae are special because they also contain transverse foramina, which are passageways for arteries leading to the brain. The two first cervical vertebrae are special, because they provide a seat for the head. C1 directly supports and balances the skull.

Which of the following is a passageway for a major blood vessel in the skull?

Carotid canal—This is the zig-zag passageway through which a major artery to the brain enters the skull. The entrance to the carotid canal is located on the inferior aspect of the skull, anteromedial to the styloid process (see Figure 6a).

What part of the vertebrae supports the head and trunk?

Cervical (neck) – the main function of the cervical spine is to support the weight of the head (about 10 pounds). The seven cervical vertebrae are numbered C1 to C7. The neck has the greatest range of motion because of two specialized vertebrae that connect to the skull.

What is atlas vertebra?

atlas: the first cervical vertebra (C1), lying directly under the skull, through which the head articulates with the neck. The main connection to the vertebra below is a pivot around the odontoid process that is an upward projection of the body of the second cervical vertebra.

What is thoracic vertebra?

Thoracic vertebrae are the twelve vertebral segments (T1-T12) that make up the thoracic spine. These structures have very little motion because they are firmly attached to the ribs and sternum (breastbone).

What passes through vertebral foramen?

function in vertebral column arch surround an opening, the vertebral foramen, through which the spinal cord passes. The centrums are separated by cartilaginous intervertebral disks, which help cushion shock in locomotion.

How many lumbar vertebrae are in the vertebral column?

The spine has three normal curves: cervical, thoracic and lumbar. There are seven cervical vertebrae in the neck, 12 thoracic vertebrae in the torso and five lumbar vertebrae in the lower back.

What is C1 vertebra called?

Atlas (C1) The atlas is ring-shaped and does not have a body, unlike the rest of the vertebrae. Fused remnants of the atlas body have become part of C2, where they are called the odontoid process, or dens.

Which vertebra is called the vertebra Prominens?

The seventh cervical vertebra is known as the vertebra prominens because of its prominent spinous process (Fig.

Which vertebrae serve as passageways for blood vessels leading to the brain?

The transverse foramina of what vertebrae serve as passageways for blood vessels leading to the brain? atlas The first vertebra is also called what? dens When the head is moved from side to side, the first vertebra pivots around the of the second vertebra.

What blood vessels supply the hindbrain and occipital lobe?

These blood vessels supply the hindbrain and the occipital lobe of the cerebrum. The vessels of the posterior circuit include: The vertebral arteries gain access to the cranial vault via the foramen magnum anterolateral to the brainstem. Concerning the branches, each vertebral artery:

Where does the posterior cerebral artery bring oxygenated blood to?

The branches of the posterior cerebral artery bring oxygenated blood to the following areas: Anterior thalamus and subthalamus Lateral wall of the third ventricle and inferior horn of the lateral ventricle Choroid plexus of third and lateral ventricles Globus pallidus Lateral and medial geniculate bodies

What part of the brain receives blood from the parietal branch?

The inferior parietal lobe, the inferior part of the superior parietal lobe, and the postcentral gyrus receive blood from the parietal branch. Several temporal arteries then go on to perfuse the lateral aspect of the temporal lobe. The posterior circulation refers to all the blood vessels that arise from the vertebrobasilar system.
