–Answer

• direct
• autocrine
• paracrine
• endocrine
• synaptic
• Describe a direct pathway communication?

–Answer Exchange of chemical messen- ger via gap junction

• Describe a autocrine pathway communication?

–Answer chemical messengers re- leased by and affected the same cell -same cell or cell type

• Describe a paracrine pathway communication?

–Answer Chemical messengers trans- fer information between two neighboring cells -located near cell -different cell type

• Describe a endocrine pathway communication?

–Answer chemical messenger reach target tissue though the blood circulation -Distant cell location -Different cell type

• Describe a synaptic pathway communication? 1 / 3

SUBSCRIBE

–Answer communicates via neurotrans- mitter across the synapse -synaptic communication occurs across synaptic cleft
