Diencephalon
Thalamus Relay center for sensory tractsfrom the spinal cord to thecerebrum. Contains centers for sensationof pain, temperature, and touch. Involved with emotions andalerting or arousal mechanisms.
The Reticular Formation
HypothalamusRegulates: autonomic control center- blood pressure,rate and force of heart contraction, centerfor emotional response and behavior body temperature water balance and thirst sleep/wake cycles appetite sexual arousal control of endocrine functioning:Acts on the pituitary gland through therelease of neurosecretions.
Hypothalamus
The Limbic SystemThe Limbic System
Midbrain Contains ascending and descendingtracts to the cerebrum andthalamus.Reflex center for eye muscles.Also involved with processing visualand auditory information (connectshead movements with visual andauditory stimuli).
Pons Connects the twohalves of thecerebellum. Regulates breathing.
Medulla Oblongata Composed of nerve tracts toand from the brain (thesetracts cross over left to rightand right to left) May be regarded as anextension of the spinal cord Almost all of the cranialnerves arise from this region
Medulla OblongataContains control centers formany subconscious activities Respiratory rate Heart rate Arteriole constriction Swallowing Hiccupping Coughing Sneezing
Cerebellum Controls and coordinatesmuscular activity. Important in equilibrium,posture and movement.

NERVI CRANIALES1. 1Кожна горлова дуга іннервується своїм власним черепним нервом.Трійчастий нерв, що іннервує першу горлову дугу, має три гілки: очну,верхньощелепну і нижньощелепну. Нервом другої дуги є лицевий нерв;нервом третьої дуги – язикогорловий нерв. Мускулатура четвертої дугиіннервується верхньою гортанною гілкою блукаючого нерва, а шосту дугуіннервує зворотна гілка блукаючого нерва.www.anatom.ua36
