True
Which lobe can result from injury due to the bony protuberances in the base of the skull
Temporal lobe
True or false
A lack of oxygen to the brain for just a few minutes can result in irreversible damage to the brain
True
What are the meninges
Layers of tissue that separate the skull and the brain
What is the largest portion the the brain
Cerebrum
What is the cerebrum’s function
It is divided into five lobes that are responsible for different functions
What are the five lobes of the brain
Frontal Temporal Occipital Parietal Limbic
What is the frontal lobe responsible for
Higher cognitive function Such as -memory -language -problem solving -etc
What is the temporal lobe responsible for
For emotion, smelling, tasting, hearing, sexual behavior
What is the parietal lobe responsible for
Plays a role in our sensations such as touch, smell, taste, and etc
What is the wernicke area. Where is it located and what is it responsible for
Responsible for matching written words with sound of spoken speech and in the parietal lobe
What is the occipital lobe responsible for
For visions and recognition
What is the limbic lobe responsible for
For the limbic system
What is the limbic system
Area of the brain that regulates emotions and memory. It directly connects the lower and higher brain functions
What is the tissue in the brain that is responsible for body movement and balance
Cerebellum
What is the hypothalamus responsible for
- controls autonomic nervous system
- emotion and behavior
- regulate body temp
- regulate food intake
- controls sleep-wake cycle
What is the medulla oblongata responsible for
Vital involuntary reflexes such as swallowing, vomiting, sneezing, coughing, and cardiovascular functions
What is the origin of many cranial nerves
The medulla
What is controls the basic functions of life such as breathing, heart rate, swallowing, sleep and etc
Brain stem
What are the three divisions of the brainstem
Midbrain
Pons
Medulla oblongata
What are the 12 cranial nerves in order
Olfactory Optic Oculomotor Trochlear Trigeminal Abducens Facial Vestibulocohlear Glossopharyngeal Vagus Accessory Hypoglossal
What does injuries to the side of the head result in
Change in language or speech and sensory or motor problems
Explain the diffuse axonal injury
Very serious injury as it impacts the major pathways of the brain
Explain epidural hematoma
Blood clot that forms between the skull and top lining of the brain
Does a epidural change fast or slow changes of pressure in the brain
Fast
Explain subdural hematoma
Blood clot that forms between the dura and the brain tissue
Does subdural hematoma cause neuron damage or tissue damage
Tissue damage
Does epidural hematoma cause neuron damage or tissue damage
Neuron damage
What is the area that we formulate speech
Broca’s area
What are the two areas of the brain for auditory aka hearing and explain them
Primary auditory -detects sounds and transmits them to ear
Auditory association- used to recognize sound as speech, music, or noise
What role does the pons play
Critical role in respiration
