What part of the brain affects hearing and seeing?
Cerebrum: is the largest part of the brain and is composed of right and left hemispheres. It performs higher functions like interpreting touch, vision and hearing, as well as speech, reasoning, emotions, learning, and fine control of movement. Cerebellum: is located under the cerebrum.
What part of the brain is responsible for hearing ability?
temporal lobe
The temporal lobe is located on the side of the head (temporal means “near the temples”), and is associated with hearing, memory, emotion, and some aspects of language.
What are the 5 parts of the brain and their functions?
- The Biggest Part: the Cerebrum. The biggest part of the brain is the cerebrum.
- The Cerebellum’s Balancing Act. Next up is the cerebellum.
- Brain Stem Keeps You Breathing — and More. Another brain part that’s small but mighty is the brain stem.
- Pituitary Gland Controls Growth.
- Hypothalamus Controls Temperature.
What does the middle brain control?
The midbrain or mesencephalon is the forward-most portion of the brainstem and is associated with vision, hearing, motor control, sleep and wakefulness, arousal (alertness), and temperature regulation.
What is this cerebrum?
(seh-REE-brum) The largest part of the brain. It is divided into two hemispheres, or halves, called the cerebral hemispheres. Areas within the cerebrum control muscle functions and also control speech, thought, emotions, reading, writing, and learning.
What does occipital lobe do?
The parietal lobe processes information about temperature, taste, touch and movement, while the occipital lobe is primarily responsible for vision.
What is brocas?
Broca’s area, or the Broca area (/ˈbroʊkə/, also UK: /ˈbrɒkə/, US: /ˈbroʊkɑː/), is a region in the frontal lobe of the dominant hemisphere, usually the left, of the brain with functions linked to speech production.
What is a neuron?
Neurons are information messengers. They use electrical impulses and chemical signals to transmit information between different areas of the brain, and between the brain and the rest of the nervous system. Neurons have three basic parts: a cell body and two extensions called an axon (5) and a dendrite (3).
What is the Broca area?
Broca’s area is also known as the motor speech area. It is near the motor cortex and utilized in speech production, located in the inferior frontal gyrus. This area regulates breathing patterns while speaking and vocalizations required for normal speech.
What is the myelin?
Myelin is an insulating layer, or sheath that forms around nerves, including those in the brain and spinal cord. It is made up of protein and fatty substances. This myelin sheath allows electrical impulses to transmit quickly and efficiently along the nerve cells.
What does the dendrite do?
Dendrite – The receiving part of the neuron. Dendrites receive synaptic inputs from axons, with the sum total of dendritic inputs determining whether the neuron will fire an action potential. Spine – The small protrusions found on dendrites that are, for many synapses, the postsynaptic contact site.
What does the soma do?
Cell body. Also known as a soma, the cell body is the neuron’s core. The cell body carries genetic information, maintains the neuron’s structure, and provides energy to drive activities. Like other cell bodies, a neuron’s soma contains a nucleus and specialized organelles.
Where is the auditory cortex located in the brain?
The auditory cortex — located in the temporal lobes of the brain, which are situated above the ears — gives meaning to the large amount of information sent to it by the inner ear and cochlear nucleus. It is the language center of the brain and its role is to interpret sounds so they are understood.
Which is part of the brain analyzes sound?
Auditory information is analyzed by multiple brain centers as it flows to the superior temporal gyrus, or auditory cortex, the part of the brain involved in perceiving sound. In the auditory cortex, adjacent neurons tend to respond to tones of similar frequency.
How does the auditory nerve work in the brain?
The auditory nerve then carries the signals to the brainstem. Because each hair cell rides on a different part of the basilar membrane, each responds to a different frequency. As a result, each nerve fiber carries information about a different frequency to the brain.
Which is part of the brain controls pupil response?
Cranial nerve 3: The oculomotor nerve controls pupil response and other motions of the eye, and branches out from the area in the brainstem where the midbrain meets the pons. Cranial nerve 4: The trochlear nerve controls muscles in the eye. It emerges from the back of the midbrain part of the brainstem.
