Chapter 1.6 (page 12) Flashcards
Enumerate the major divisions of the brain in descending order.
Cerebrum
Diencephalon
Cerebellum
Brainstem
What are the three parts of the brainstem?
Medulla Oblongata
Pons
Midbrain
Gray matter of the brainstem functions as ________________________; for heartbeat, respiration, etc:
Autonomic Reflex Centers
In the brainstem, _______________ conduct impulses to higher centers of the brain.
Sensory tracts
In the brainstem, ____________ conduct impulses from the higher centers of the brain to the spinal cord.
Motor tracts
The cerebellum is the second largest part of the brain and is connected to the brainstem by _________, ______, and ________ peduncles.
Superior peduncle
Middle peduncle
Inferior peduncle
The __________ helps control muscle contractions to produce coordinated movements so that we can maintain balance, move smoothly and sustain posture.
Cerebellum
What part of the brain forms the central core of the forebrain?
Diencephalon
The diencephalon consists of two major structures which are ____________ and ________.
Hypothalamus
Thalamus
The hypothalamus acts as the major center for controlling the ________________________; helps control function of most internal organs. It also controls hormone secretion and contains the centers for controlling appetite, wakefulness, pleasures and etc.
Autonomic Nervous System
A part of the diencephalon which is the major relay station for the sensory impulses ascending to the cerebral cortex.
Thalamus
What is the largest part of the human brain and is composed of two cerebral hemispheres?
Cerebrum
What partially separates the hemispheres of the cerebrum?
Longitudinal Fissure
Each cerebral hemisphere consists of three layers. What are they?
Cerebral cortex
Cerebral white matter
Cerebral nuclei
This layer of the cerebrum consists mostly of dendrites and cell bodies of neurons.
Cerebral Cortex
