Cerebellum
Cerebrum
Lobe, Gyrus, Sulcus
coordination center, body position,
balance center
Thalamus
Limbic system
Hipothalamus
autonomic nervous control, thermoregulator, hunger center and thirst, connecting the nervous system with the system endocrine
central station for receiving sensory impulses except olfaction
cortex, thalamus and central hypothalamus regulation of human emotions and feelings
Mesencephalon ( Mid brain )
Hearing center, visual reflex, innervation pathways between the cerebral hemispheres and the cerebellum
Pons
Controls breathing
Medulla oblongata
Heart rate, blood pressure, respiration and swallowing
Somatic nervous system
Autonomic nervous system
The nerves that carry information to the sensory and motor nerves of the central nervous system consist of 12 pairs of cranial nerves and 31 pairs of spinal nerves
Regulates unconscious body tissues and organs the tissues and organs of the body are regulated by the nervous system autonomic is the blood vessels and the heart which consists of sympathetic and parasympathetic nervous system
Sympathetic nerves
Parasympathetic nerves
are nerves that originate in the spinal cord chest area and also the waist, which serves to spur and speed up the work of the organs of the human body, for example speeding up the heartbeat and causing contractions blood vessel
is a nerve that originates from the advanced marrow (medulla oblongata) and from the sac which is the pre-ganglionic and post-ganglionic nerves, these nerves serves to slow down the work of the organs of the body, for example reduce heart rate, narrow the respiratory tract.
