- What structures are included in the CNS (central nervous system)?
- Brain and spinal cord.
- A student pulls their hand away from a flame before they cry out in pain. Why does this occur?
- A reflex arc pathway was followed from stimulus to muscle without the need of the brain. Comprehension of pain comes later.
- What types of neurons are only found within the brain or spinal cord?
- Interneurons or association neurons.
- PNS neurons have a myelin sheath. How does this speed up nervous transmission?
- An impulse can jump or hop from Node to Node without having to traverse the entire length of the axon.
- Autonomic nervous pathways are generally found within this branch of the nervous system
- PNS or peripheral nervous system.
- The brain is a vital organ and is protected in many ways. List three ways the brain is protected.
-
Bone (Skull)
Fluid (CSF)
Meninges (3 layers - Sensory neurons enter the spinal cord through the ______ root.
- Dorsal root, or the back of the spinal cord.
- Motor neurons leave the spinal cord through the ______ root.
- Ventral root, or the front of the spinal cord.
- Neurons that are directly connected to an effector are known as
- motor neurons.
- The first neuron to respond to a stimuli is a
- sensory neuron.
- The region of the brain that controls autonomic functions is the
- Medula Oblongata.
- The region of the brain that coordinates muscle movement and balance is the
- Cerebellum.
- The lobe of the brain that holds our personality, judgement and emotion is the
- frontal lobe.
- The lobe of the brain responsible for vision is the
- occipital lobe.
- The lobe of the brain that responds to touch and external sensation is the
- parietal lobe.
- The lobe of the brain most involved in hearing smell and taste is the
- temporal lobe.
- The region of the brain that reponds to a lack of water in the body would be the
- Hypothalamus.
- The region of the NS responsible for control of the endocrine system would be the
- Hypothalamus.
- The structure in the brain that communicates information between the hemispheres is the
- Corpus Callosum.
- A nervous system condition that is characterized by uncontrolled impulses is known as
- Epilepsy
- If medication fails to stop Grand Mal seizures from occuring, this region can be cut in the brain.
- The corpus callosum.
- A young man suffers brain damage during a rig accident. Afterward he experiences a dramatic change in personality. The region most likely damaged is the
- frontal lobe.
- The decision to begin walking down the street originates in this area of the brain
- The frontal lobe.
- The coordination of fingers while playing the piano is controled by the
- cerebellum.
- Sequential skills such as speaking, reading, or doing arithmetic, are processed mainly in the ________________ hemisphere
- left (hemisphere)
- Spatial skills such as sketching or reading a map are primarily processed in the __________ hemisphere.
- right (hemisphere)
-
Structure A is known as the - cerebrum or cerebral cortex.
-
The structure that is responsible for communication between the hemispheres is labelled - B (corpus callosum)

-
The lobe responsible for vision is labeled - D (occipital lobe)
-
The lobe responsible for hearing and smell is labeled - C (temporal lobe)
-
The lobe responsible for sensation of touch is labeled - B (parietal lobe)
-
The region of the brain responsible for life critical functions is labeled - C (hind brain)
-
The region of the brain most developed in "higher" mammals is labeled - A (fore brain)
-
The midbrain is labeled - B
-
The sensory neuron is labeled - 2
-
This diagram illustrates a - reflex arc.
-
The neuron labeled 4 is - an interneuron or association neuron.
-
The part of the spinal cord labeled 3 is known as the - dorsal root ganglion.
