Question

diagramme suivante, les flèches représentent le trajet de linflux nerveux. nomme chaque structure. entre parenthèses si elle appartient au snc ou au snp.

Explanation:

To solve this problem about the nervous system (SNC: Système Nerveux Central; SNP: Système Nerveux Périphérique), we analyze the structures:

1. Structures of the Central Nervous System (SNC)

• Cerveau (SNC): The brain, part of the central nervous system (processes information).
• Moelle épinière (SNC): The spinal cord, also part of the central nervous system (transmits signals between brain and body).
• The box grouping brain and spinal cord is labeled as Système Nerveux Central (SNC) (includes brain + spinal cord).

2. Structures of the Peripheral Nervous System (SNP)

• Nerf crânien (SNP): Cranial nerve (connects brain to head/neck, part of peripheral system).
• Nerf spinal (SNP): Spinal nerve (connects spinal cord to body, part of peripheral system).
• Récepteur (SNP): Receptor (e.g., in skin/muscle, detects stimuli, part of peripheral input).
• Effecteur (SNP): Effector (e.g., muscle/gland, responds to signals, part of peripheral output).

Labeling Example (from top to bottom, left to right):

• Top - left 1: Cerveau (SNC)
• Top - left 2: Moelle épinière (SNC)
• Top - left 3: Nerf crânien (SNP)
• Middle - left: Récepteur (SNP)
• Middle - right: Effecteur (SNP)
• Bottom - right: Nerf spinal (SNP)
• Top - right box: Système Nerveux Central (SNC)

(Note: The exact labels depend on the diagram’s specific arrows, but this follows the SNC/SNP classification: SNC = brain + spinal cord; SNP = nerves, receptors, effectors connecting SNC to body.)
