Brain Structures and Functions Flashcards

Vocabulary flashcards focusing on key brain structures, lobes, limbic system components, and speech/cortex areas provided in the lecture diagrams.

frontal lobe

The anterior region of the cerebral cortex involved in high-level executive functions, decision-making, planning, and voluntary motor control.

parietal lobe

The lobe of the cerebral cortex located posterior to the frontal lobe, responsible for processing sensory information such as touch, temperature, and spatial awareness.

occipital lobe

The posterior region of the cerebral cortex containing the primary visual processing center of the brain.

temporal lobe

The region of the cerebral cortex situated below the frontal and parietal lobes, involved in processing auditory information, language comprehension, and memory.

cerebellum

A structure located at the base of the brain posterior to the brainstem, responsible for coordinating voluntary movements, posture, and balance.

medulla oblongata

The lower portion of the brainstem, positioned inferior to the pons, that regulates crucial autonomic functions such as heart rate and respiration.

corpus callosum

A thick band of nerve fibers in the medial brain section connecting the left and right cerebral hemispheres, facilitating interhemispheric communication.

cerebral cortex

The outer neural tissue layer covering the cerebrum, critical for higher-order cognitive functions, perception, and voluntary action.

thalamus

A central brain structure positioned superior to the hypothalamus, serving as a relay station for sensory information sent to the cerebral cortex.

hypothalamus

A structure located inferior to the thalamus that regulates autonomic body functions, homeostasis, and endocrine activity via the pituitary gland.

pons

A brainstem structure located superior to the medulla oblongata and inferior to the thalamus, involved in relaying sensory signals and regulating sleep and arousal.

pituitary

An endocrine gland located beneath the hypothalamus that synthesizes and releases hormones controlling bodily growth and metabolic activity.

hippocampus

A limbic system structure located near the amygdala, essential for spatial navigation and the consolidation of short-term memory into long-term memory.

amygdala

An almond-shaped neural structure in the limbic system involved in memory processing and emotional responses, particularly fear and aggression.

motor cortex

A region of the cerebral cortex located in the frontal lobe responsible for planning, controlling, and executing voluntary motor movements.

Sensory Cortex

A region of the cerebral cortex located in the parietal lobe immediately posterior to the motor cortex, responsible for processing tactile and bodily sensations.

Wernicke's area

A specialized region near the junction of the temporal and parietal lobes involved in spoken and written language comprehension.

angular gyrus

A parietal lobe region located near Wernicke's area and the visual cortex, playing a key role in language comprehension, visual processing, and reading.

visual cortex

A region within the occipital lobe that processes visual input received from the retinal pathways.

Broca's area

A region in the frontal lobe involved in speech production, language articulation, and grammatical processing.

auditory cortex

A region located in the temporal lobe responsible for processing sound perception, tone, and auditory stimuli.
