Spinal Nerve/Cord Model

Location: Where is the Gray commissure located?

• 8

• 2

• 25

Function: What is the function of Gray commissure?

• The Gray commissure is responsible for motor control in the limbs.
• The Gray commissure produces cerebrospinal fluid.
• The Gray commissure connects the left and right sides of the spinal cord.

Location: Where is the Posterior (dorsal) horn located?

• 5

• 7

• 6

Function: What is the function of the Posterior (dorsal) horn?

• The posterior horn regulates blood flow in the spinal cord.
• The function of the posterior (dorsal) horn is to process and transmit sensory information.
• The posterior horn is involved in hormone secretion.

Location: Where is the Lateral horn?

• 5

• 6

• 7

Function: What is the function of the lateral horn?

• The lateral horn controls voluntary muscle movements.
• The lateral horn is involved in the production of hormones.
• The function of the lateral horn is to regulate autonomic functions through sympathetic nervous system pathways.

Location: Where is the Anterior (ventral) horn?

• 5

• 6

• 7

Function: What is the function of the Anterior (ventral) horn?

• The anterior horn regulates blood pressure and heart rate.
• The anterior horn is involved in the production of cerebrospinal fluid.
• The anterior (ventral) horn is responsible for motor control, specifically the innervation of skeletal muscles.

Location: Where is the central canal?

• 9

• 3

• 8

Function: what is the function of the central canal?

• The central canal stores nutrients for nerve cells.
• The central canal transports oxygen to the brain.
• The central canal functions to circulate cerebrospinal fluid within the spinal cord.
