Frontal lobe is stimulated; you perceive a threat and react 5. Visual centers in the occipital lobe interpret the stimuli Select one: a. 1, 2, 3, 4, 5 b. 5, 2, 3, 1, 4 c. 2, 3, 5, 4, 1 d. 5, 2, 3, 4, 1 Clear my choice

d. Damage to Broca’s area makes him unable to understand instructions

Answer 1

1. c. 2, 3, 5, 4, 1

Explanation:

2. Receptors in the eye detect something

3. Stimulation of the optic nerve

5. Visual centers in the occipital lobe interpret the stimuli

4. Frontal lobe is stimulated; you perceive a threat and react

1. Motor centers send a message down efferent nerves to run away

2. Temporal lobe

Explanation: An injury to a temporal lobe could result in difficulties in recognizing faces, understanding spoken words, and identifying objects, as well as short-term memory loss.

3. a. Damage to the brain stem leads to cardiac failure

Explanation: Vital centers for the body functions are located in the brainstem such cardiovascular and respiratory centers. Damage to brainstem could result in sudden death.
