Chapter 3 Ppt Learning Check Flashcards
Together, the somatic nervous system and the autonomic nervous system make up the ———- nervous system.
Peripheral
Which division of the nervous system consists of neurons that deliver messages from the sensory organs to the central nervous system?
Somatic
Which plane shows the brain structures as they would be seen from the front?
Coronal
If one structure is on the left side and another is on the right, they are said to be —— to each other.
Contralateral
After damage to the dorsal roots of the spinal cord, an individual will suffer what kind of loss?
Sensation from the affected body area
After damage to the central roots of the spinal cord, an individual will suffer what kind of loss?
control of the peripheral muscles in the affected body area
Cell bodies of sensory neurons are located in the ——- ——– ——-.
Dorsal root ganglia
A cross section of the spinal cord indicates that grey matter is —————-.
Densely packed with cell bodies and dendrites
The sweat glands, adrenal glands, and muscles that construct blood vessels have input from only the ——— nervous system.
Sympathetic
Sympathetic ganglia ———–.
Are closely linked and often act as a single system
What structure is composed of the medulla, pons, the midbrain, and certain structures of the forebrain?
Brain stem
Breathing, heart rate, vomiting, salivation,coughing, and sneezing are all controlled by which structure?
Medulla
The nuclei for most of the cranial nerves are located in the ———-.
Pons and medulla
Note:
- cranial nerves I through IV are located in the midbrain and forebrain
- cranial nerves V through XII are located in the pons and medulla
In which area of the brain should one find the tectum, tegmentum, superior and inferior colliculi , and substantia nigra ?
Mindbrain
The limbic system is most related to ——— ———.
Emotional behaviors
An imparement of eating, drinking, temperature regulation, or sexual behavior suggests possible damage to which brain structure?
Hypothalamus
Damage to the basal ganglia would most likely result in ———- ——–.
a mobility disorder
Note: basal damage can cause problems with speech, movement and posture
The ventricles, central canal, and subarachnoid space are all ———–.
Filled with cerobrospinal fluid
Meningitis is an inflammation of the ——–.
Membranes surrounding the brain ( AKA meninges)
Cortical blindness may result from the destruction of ———.
The occipital cortex
Which part of the cerebral cortex is most important for the sense of touch?
Temporal lobe
What is the primary target area in the cortex for information regarding muscle-stretch and joint receptors?
Primary somatosensory cortex
Hint:
Sensory in somatosensory refers to information received from outside the body.
The precentral gurus is essential for the ———-.
Coordination of fine movements
Neurons in the prefrontal cortex —————— that neurons in other cortical areas.
Have more dendritic spikes
