what function do fibroblasts serve in connective tissue?
secrete heparin that prevents blood clotting
carry on phagocytosis
release histamine associated with allergies and inflammation
secrete proteins that become fibers in the connective tissue matrix

Explanation:

• Reflex arc: A reflex arc is the neural pathway that controls a reflex. It consists of a sensory receptor (detects the stimulus), an afferent (sensory) neuron (transmits signal to the central nervous system), a control center (in the spinal cord or brainstem), an efferent (motor) neuron (transmits signal from the control center to the effector), and an effector (muscle or gland that responds).
• Fibroblasts: Fibroblasts are cells in connective tissue. Their main function is to secrete proteins (such as collagen and elastin) that form the fibers in the connective tissue matrix.

Answer:

• First question (reflex arc): Control center, Sensory receptor, Efferent neuron.
• Second question (fibroblasts): Secrete proteins that become fibers in the connective tissue matrix.
