-
The somatic efferent neuron and the second neuron of the sympathetic division of the autonomic nervous system.
-
The somatic efferent neuron and the second neuron of the parasympathetic division of the autonomic nervous system.
Pregunta 2
Pregunta
Which statements about the external anatomy of the spinal cord are true?
Respuesta
-
It ends at the superior border of the second lumbar vertebrae. (L2).
-
It leaves the skull though the foramen magnum.
-
It is within the meningeal sack, which sits inside the spinal cavity.
-
The spinal cavity surrounds the vertebrae.
Pregunta 3
Pregunta
The CSF (cerebrospinal fluid) is to provide cushioning as well as nutrients.
Respuesta
- True
- False
Pregunta 4
Pregunta
From the deepest part to the most superior part, the spinal cord is protected by CSF > Adipose Tissue > Meninges > Vertebrae
Respuesta
- True
- False
Pregunta 5
Pregunta
Which statement about the external anatomy of the associated features of the spinal cord is false?
Respuesta
-
The conus medularis and filum terminale are connective tissue.
-
The filum terminale is an extension of the nerves.
-
The conus medularis is a tapered cone at the distal end of the spinal cord/meningeal sack.
Pregunta 6
Pregunta
Spinal nerves are named after the vertebrae/spinal cord region they exit/enter. The spinal cord, from superior region to most inferior region, goes Cervical > Thoracic > Lumbar > Sacrum.
Respuesta
- True
- False
Pregunta 7
Pregunta
Inferior to the end of the spinal cord, some lumbar and all sacral nerves continue to exit the vertebral column.
Respuesta
- True
- False
Pregunta 8
Pregunta
Which statement about the cauda equina is false.
Respuesta
-
It is the region of the meningeal sack inferior to the spinal cord.
-
At its most inferior point, spinal nerves exit the cauda equina at the coccygeal level.
-
The existence of the cauda equina means that you can only damage your spinal nerves if the spinal cord is damaged.
Pregunta 9
Pregunta
The central canal is more of a theoretical or potential space than a real space.
Respuesta
- True
- False
Pregunta 10
Pregunta
White matter is cell bodies.
Respuesta
- True
- False
Pregunta 11
Pregunta
Which of these statements about the internal anatomy of the spinal cord is correct?
Respuesta
-
Neurons leaving the ventral root always synapse with skeletal muscle.
-
The dorsal root ganglion carries afferent information to the brain.
-
The anterior region of the spinal cord carries ascending information.
-
Damage to the posterior region of the spine affects motor control.
Pregunta 12
Pregunta
The dorsal root ganglia and the sympathetic chain ganglia are the same thing.
Respuesta
- True
- False
Pregunta 13
Pregunta
The dorsal root ganglion contain cell bodies of neurons which are unipolar.
Respuesta
- True
- False
Pregunta 14
Pregunta
A spinal nerve contains both afferent and efferent information.
Respuesta
- True
- False
Pregunta 15
Pregunta
The ventral ramus is one of two diverging paths from a spinal nerve, which brings both afferent and efferent information to the posterior of the body.
Respuesta
- True
- False
Pregunta 16
Pregunta
The sympathetic chain ganglia diverge from the dorsal ramus.
Respuesta
- True
- False
Pregunta 17
Pregunta
A bundle of axons in the PNS is called a tract.
Respuesta
- True
- False
Pregunta 18
Pregunta
A nerve is fascicles surrounded by perineurium containing axons surrounded by endoneurium, bundled together with blood vessels and surrounded by epineurium.
Respuesta
- True
- False
