Choose the letter that best answers each of the statements below. Patients with high level cervical spinal cord transections have considerable disturbance of thermoregulation and are very prone to hypo- or hyperthermia. A. Homeostatic responses to hypothermia require descending connections from the anterior hypothalamus to the spinal cord. B. Homeostatic responses to hypothermia require descending connections from the posterior hypothalamus to the spinal cord.
Many pathways connect the hypothalamus to the limbic system and the visceral system.
The suprachiasmatic nucleus communicates with the pineal gland by the medial forebrain bundle to control sleep. The mammillotegmental tract descends from the hypothalamus to the mammillary body to control feeding behavior. The medial forebrain bundle connects the hypothalamus and the cingulate gyrus to influence voluntary behaviors. The amygdala is connected to the hypothalamus by the fornix. The dorsal longitudinal fasciculus descends through the brainstem and spinal cord and directly innervates both parasympathetic and sympathetic preganglionic neurons.
