Spinal Cord Flashcards
ID the structure indicated by J
Anterior median fissure
ID the structure by A.
Posterior median sulcus
ID the structure by H. What do you find here?
Anterior gray horn. Cell bodies for somatic motor neurons —> axon project out and control skeletal muscle
ID the structure indicated by F. What it’s function? What does it contain?
Lateral gray horn. Responsible Motor functions. Cell bodies of autonomic motor neurons.
What effectors do autonomic motor neurons have?
Have effectors of smooth muscle, cardiac muscle, or glands
ID the structure indicated by C. What do they contain?
Posterior grey horns. Somatic & autonomic sensory information.
ID the structure indicated by B.
Posterior white column.
Information is being transmitted
contains axons.
ID the structure indicated by D.
Lateral white column
ID the structure indicated by I
Anterior white column.
ID the structure indicated by E
Gray commissure. A strip of gray matter that surrounds the central canal of the spinal cord.
ID the structure indicated by 8. What does it contain?
Anterior gray horn. Cell bodies of somatic motor neurons where skeletal muscle contractions is initiated from the spinal cord.
ID the structure indicated by 5. What does it contain?
Lateral gray horn. Autonomic motor neurons the effectors are cardiac muscle, smooth muscle, glands.
ID the structure 11.
Posterior gray horn. Sensory information comes in
ID the structure indicated by 10.
Posterior white column
ID the structure indicated by 4
Lateral white column
ID the structure indicated by 6
Anterior white column
ID the structure.
Dorsal roots
ID the structure indicated by the pointer. What’s is it?
Dorsal root ganglia.
The cell bodies of the sensory neurons in the dorsal roots in the dorsal root ganglia. Each ganglia is attached to the dorsal root. They carry sensory signals to the dorsal gray horn of the spinal cord.
ID the structure indicated by the pointer
Ventral root
ID the structure by the pointer.
Ventral rami. Branch of the nerve branches anterior
ID the structure by the pointer.
Dorsal rami. Branch of the nerve branches posterior
ID the structure indicated by the pointer
Rami communicantes.autonomic motor neurons
ID the structure indicated by the pointer.
Epidural space.it’s filled with adipose tissue/ epidural fat
ID the structure
Dura mater ( tough mother): layer is dense connective tissue stabilizes the brain & spinal cord.
ID the volumetric space
Subarachnoid space. Where Cerebral fluid flows.
ID the structure
Pia mater(gentle mother): stabilizes smaller blood vessels
