Answer:
The cerebellum.
Explanation:
The cerebellum receives information from the sensory systems, the spinal cord, and other parts of the brain and then regulates motor movements. The cerebellum coordinates voluntary movements such as posture, balance, coordination, and speech, resulting in smooth and balanced muscular activity.
Answer:
Proper sequence of events:
5. Sensory receptor detects change in the environment.
2. Afferent neuron graded potential reaches threshold and fires an action potential.
4. CNS reaches decision about response.
1. Efferent neuron graded potential reaches threshold and fires an action potential.
3. Target organ responds.
Explanation:
Sensorial information is received by the peripheral nervous system and processed by the central nervous system. There are three types of neurons involved in this transmission: sensory or efferent neurons, interneurons, and motor or efferent neurons. First <em>stimulus energy is received</em> by sensory receptors specialized in responding to <em>different stimuli</em>. Then it occurs the <em>transduction or conversion</em> of the stimulus energy (chemical, temperature, light, pressure, etc.) to action potential energy. The afferent neurons, located in dermis and epidermis, <em>receive information</em> from the sensory receptors, react to stimuli and <em>transmit impulses</em> to the central nervous system. This pathway is defined as the <u>ascending pathway</u>. Information is <em>processed</em> in the central nervous system by the <em>interneurons</em> which handle many sensory signals, evaluate them, compare them and use them for <em>decision making.</em> After that, an efferent neuron is stimulated to <em>carry signals</em> from the central nervous system to the <em>effectors' cells</em> of the target organ. The effector may be muscle or glandular tissue. This pathway is defined as the <u>descending pathway</u>. Finally, the target organ responds by contracting or hormone-releasing.
