What is the correct order for the parts of the spinal cord from superior to inferior?

What is the correct order for the parts of the spinal cord from superior to inferior?

What are the vertebral classifications, from superior to inferior? Explanation: The spinal cord and vertebrae is broken down into four regions: cervical, thoracic, lumbar, and sacral.

What are the regions of the spinal cord?

The spinal cord and spine are divided into 4 regions from top to bottom: cervical, thoracic, lumbar, and sacral. Damage to the nerves in the spinal cord can result in many health conditions, depending on the region that is affected.

Where does the spinal cord begin and end?

The spinal cord is an extension of the central nervous system (CNS), which consists of the brain and spinal cord. The spinal cord begins at the bottom of the brain stem (at the area called the medulla oblongata) and ends in the lower back, as it tapers to form a cone called the conus medullaris.

What are the 7 process of vertebrae?

There are seven cervical vertebrae (but eight cervical spinal nerves), designated C1 through C7. These bones are, in general, small and delicate. Their spinous processes are short (with the exception of C2 and C7, which have palpable spinous processes). C1 is also called the atlas, and C2 is also called the axis.

What are the five major regions of the vertebral column?

The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.

How many tracts are there in the spinal cord?

However, the other tactile modalities are transmitted through the ascending tracts of the spinal cord. There are eight known ascending tracts conveying a variety of sensory stimuli that are discussed below.

What are the 4 major nerve plexuses?

Of the four major nerve plexuses (cervical, brachial, lumbar, and sacral), only the brachial plexus and sacral plexus can be assessed satisfactorily in the EDX laboratory.

What is the correct order of meninges from outside to inside?

In order from the outermost to innermost layer, the meninges are: dura mater, arachnoid mater, arachnoid space, and pia mater.

Which pathways are made up of three neurons?

The dorsal column system (sometimes referred to as the dorsal column–medial lemniscus) and the spinothalamic tract are two major pathways that bring sensory information to the brain (Figure 14.5. 1). The sensory pathways in each of these systems are composed of three successive neurons.

What are the 5 levels of the spinal cord?

As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx. Did you know? Only the top 24 bones are moveable. The vertebrae of the sacrum and coccyx are fused.

What are the 5 major regions of the vertebral column quizlet?

The five major regions of the vertebral column are the cervical region, thoracic region, lumbar region, sacrum, and coccyx.

What are the 6 major tracts of the spinal cord?

We have plotted the position of six descending tracts (corticospinal, rubrospinal, medial and lateral vestibulospinal, rostral and caudal reticulospinal) and eight ascending tracts (gracile; cuneate; postsynaptic dorsal columns; dorsolateral, lateral, and anterior spinothalamic; dorsal and ventral spinocerebellar) on …

What are the major ascending tracts?

There are three types of ascending tracts, dorsal column-medial lemniscus system, spinothalamic (or anterolateral) system, and spinocerebellar system. They are made up of four successively connected neurons.
