12.14.5 The Human Brain

Question 1

The Human Brain

Answer 1

• The functions of the human brain include sensory interpretation, reflex actions, thought, coordination, memory, emotions, and linkage to other organ systems.
• The three major parts of the human brain are the cerebrum, the brain stem, and the cerebellum.
• The human brain stem includes the medulla oblongata, the pons and the midbrain. Much of its function involves relaying information.
• The diencephalonincludes the thalamus and the hypothalamus. The thalamus and the hypothalamus have many functions including maintaining body temperature, controlling hunger, thirst, sexual response, and pleasure and acting as a link to the endocrine system

Question 2

central nervous system

Answer 2

• The central nervous system consists of the brain and the spinal cord. The three major parts of the brain include the brain stem, the cerebrum, and the cerebellum.

Question 3

brain stem

Answer 3

• The brain stem consists of three major parts: the
  medulla oblongata, the pons, and the midbrain.
• The medulla oblongata functions as a relay switch. It relays information to the thalamus. The thalamus then relays information to the cerebrum, where the processing of information occurs.
• The pons relays information to the cerebellum and the
  thalamus. The pons also has some involuntary autonomic functions such as breathing.
• The mesencephalon, or midbrain, relays visual and auditory data to the cerebrum. It also maintains consciousness.

Question 4

diencephalon

Answer 4

• The diencephalon is above the midbrain and consists of two parts, the thalamus and the hypothalamus. The hypothalamus controls temperature, hunger, thirst, mating, sexual response, and pleasure. The hypothalamus also serves as a link to the endocrine system and is involved in maintaining circadian rhythms.
