Functions of Brain Structures
Regulates coordination of skilled movements.
Cerebellum
Three subdivisions of the brainstem
Midbrain
Pons
Medulla
A complex hierarchical structure composed of around 86 billions neurons
The nervous system
Make up half brain tissue and provide support and nutrients to the neurons
Glial Cells
What is the function of Wernicke's area?
What is involved with comprehending speech and language, including reading
Houses cranial nerve nuclei
Pons
All pathways to and from the cerebrum pass through the _____
Brainstem
three subdivisions of the CNS (cerebral hemisphere, brainstem, spinal cord)
Major components of the nervous system
True or False
Astrocytes supply nutrients and ion and neurotransmitter regulation at the synapse
True
is also referred to as expressive aphasia or non-fluent aphasia
What is Broca's Aphasia?
Mediates auditory and visual reflexes, maintains cortical arousal, houses cranial nerve nuclei.
Midbrain
True or False:
The brainstem contains cranial nerve nuclei.
The brainstem contains afferent and efferent pathways.
True
Part of the Central Nervous System
Communicate between neurons
Interneurons
The cranial nerve providing impulses to move the tongue for speech sound articulation and swallowing.
What is cranial nerve IX?
Controls the tone and movements of the muscles.
Basal Ganglia
The ________ contains cranial never nuclei XI glosspharyngeal (swallowing), X vagus (larynx), XI accessory (sternocleidomastoid), and XII hypoglossal (tongue)
Medulla
12 cranial nerves and 31 pairs of spinal nerves
Peripheral nervous system (PNS)
Bipolar neuron that activate muscular or glandular responses and usually long myelinated axons.
Motor neuron
This is the nerve that controls tongue movement for speech sound articulation (l, t, and n) and swallowing
What is the hypoglossal nerve (CN XII)?
Controls temperature, satiety, hydration balance, emotional behavior, and sexual response, among other bodily processes.
Hypothalamus
The brainstem has nuclei associated with which cranial nervers?
what is Cranial Nerves II through XII
central nervous system, peripheral nervous system, autonomic nervous system, somatic nervous system, pyramidal tracts, and extrapyramidal tracts.
Anatomical Divisions of the Nervous System
Glial cells that make up PNS myelin
Schwann cells
This nerve provides impulses for these three functions: the movement of the facial expression muscles, taste and secretion of saliva and tears.
What is the facial nerve (CN VII)?
