30.9: Vertebrate Brain

Question 1

Cerebrum

Answer 1

Localizes, processes sensory inputs; initiates, controls skeletal muscle activity; governs memory, emotions, abstract thought in the most complex vertabrates
+Forebrain

Question 2

Olfactory lobe

Answer 2

Relays sensory input from nose to olfactory centers of cerebrum
+Forebrain

Question 3

Thalamus

Answer 3

Has relay stations for conducting sensory signals to and from cebral cortex, has role in memory
+Forebrain

Question 4

Hypothalamus

Answer 4

With pituitary gland, a homeostatic control center. Adjusts volume, composition, temp of internal environ; governs organ related behaviour (sex, thirst, hunger) and expression of emotion
+Forebrain

Question 5

Limbic System

Answer 5

Governs emotions; has roles in memory

+Forebrain

Question 6

Pituitary gland

Answer 6

With hypothalamus, provides endocrine control of metabolism, growth, and development
+Forebrain

Question 7

Pineal gland

Answer 7

Helps control some circadian rythyms; also has role in mammalian reproduction
+Forebrain

Question 8

Roof of midbrain (tectum)

Answer 8

In fishes and amphibians, it centers coordinate sensory input (as from optic lobes), motor responses. In mammals, its reflex centers swiftly relay sensory input to forebrain
+Midbrain

Question 9

Pons

Answer 9

Tracts bridge cerebrum and cerebellum, also connect spinal cord with forebrain. With the medulla oblongata, controls rate and depth of respiration
+Hindbrain

Question 10

Cerebellum

Answer 10

Coordinates moto activity for moving limbs and maintaining posture, and for spatial orientation
+Hindbrain

Question 11

Medulla Oblongata

Answer 11

Tracts relay signals between spinal cord and pons; its reflex centers help control heart rate, adjustments in blood vessel diamter, respitory rate, vomiting, coughing, other vital functions
+Hindbrain
