THE HUMAN BRAIN (SCIENCE) Flashcards
The human brain is protected and encased in a bone called the?
Skull
The human brain is protected by three thin layers of tissue called?
Meninges
The human brain is bathed and cushioned from shock by a colorless fluid called?
CSF (cerebrospinal fluid)
TRUE OR FALSE. There are approximately 100 billions of neurons in a mature human brain.
True
This is largest region/part of the human brain.
Cerebrum
The surface of the cerebrum is called?
Cerebral cortex
In the cerebrum, there are three main components that occur, what are they?
- Learning
- Intelligence
- Judgment
TRUE OR FALSE. The cerebrum controls involuntary actions.
False
Answer: The cerebrum controls voluntary actions
The human brain is divided into two hemispheres called?
Right and left hemispheres
What does the right and left hemispheres do? Differentiate them.
Right hemisphere: controls the left side of the body.
Left hemisphere: controls the right side of the body.
There are four cerebral lobes, what are they?
- Frontal Lobe
- Parietal Lobe
- Occipital Lobe
- Temporal Lobe
A cerebral lobe that involves problem solving, judgment, reasoning, and voluntary movements.
Frontal Lobe
A cerebral lobe that involves the sense of touch, taste, and smell, math calculations, and academic skills.
Parietal Lobe
A cerebral lobe that involves reading and visual interpretation.
Occipital Lobe
A cerebral lobe that invovles memory, hearing, feelings, and musical awareness.
Temporal Lobe
It connects the right and left hemispheres of the brain
Corpus Callosum
It regulates balance, posture, movement and muscle coordination.
Cerebellum
Connects the cerebrum with the cerebellum.
Pons
Controls involuntary actions, such as heartbeat, breathing, and blood pressure.
Medulla Oblongata
Serves as the relay station by directing messages from the spinal cord.
Thalamus
Monitors internal conditions to keep your body in a stable state. (homeostasis)
Hypothalamus
A gland attached at the base of the brain that secretes hormones.
Pituitary Gland
A thick bundle of nerve fibers that runs from the base of the brain to the hip area.
Spinal Cord
TRUE OR FALSE. The spinal cord relays nerve impulse to and from the brain.
TRUE
What protects the spinal cord?
- The spinal column/spine/backbone
- Meninges
- CSF (cerebropinal fluid)
It is a sudden and involuntary response to a stimulus.
