Four lobes
What is the basic unit of the nervous system?
Neuron
Which part of the brain is responsible for movement and coordination?
Cerebellum
What transmits signals from the body to the brain?
Sensory neurons
Which part of the nervous system comprises the brain and spinal cord?
Central Nervous System (CNS)
The cerebrum is the largest part of the brain and is divided into two lobes: frontal and parietal.
False
The brain stem includes the mid brain, pons, and medulla oblongata, and it controls voluntary actions.
False
The nervous system comprises the brain and spinal cord, and the peripheral nervous system (PNS) is a network of nerves spread across the body.
True
The cerebrum is divided into right and left hemisphere, each with four lobes: frontal, parietal, occipital, and ______
temporal
The nervous system includes the brain and spinal cord, which together form the central nervous system (CNS), and the peripheral nervous system (PNS) is a network of nerves spread across the ______
body
Sensory neurons transmit signals from the body to the brain through ______ neurons
afferent
Study Notes
- Brain is a sensitive organ responsible for physical activity, logical problem solving, emotions, feelings, and creativity, kept inside the skull
- Three main parts of the brain: cerebrum, cerebellum, and brain stem
- Cerebrum is the largest part, divided into right and left hemisphere, each with four lobes: frontal, parietal, occipital, and temporal
- Cerebellum responsible for movement and coordination, gives sense of balance
- Brain stem includes mid brain, pons, and medulla oblongata, controls involuntary actions
- Nervous system includes the brain and spinal cord, CNS and PNS
- CNS comprises the brain and spinal cord, PNS is a network of nerves spread across the body
- Sensory neurons transmit signals from body to brain through afferent neurons
- Motor neurons respond by sending signals back through efferent neurons
- 43 pairs of nerves in PNS, 12 cranial and 31 spinal
- Neuron is the basic unit of nervous system, made up of dendrites, soma, and axon.
