Exam 14: Integration of Nervous System Functions

In an ascending pathway, axons of the secondary neuron travel from the

-What is the function of the sensory receptor of the skin labeled "A"? A) Detects deep pressure, vibration, and proprioception B) Responds to painful stimuli and temperature C) Responds to light touch and superficial pressure D) Detects touch, involved in 2-point discrimination E) Detects continuous touch or pressure

Various areas of the cortex form functional pathways to conduct action potentials necessary to perform specific functions. Arrange the areas below in proper sequence to accomplish reading a poem aloud. (1) Visual association area (2) Premotor area (3) Broca area (4) Primary motor area (5) Wernicke area (6) Visual cortex
