Anatomy of the Brain Flashcards
Learn its names and functions
What is the Frontal Lobe’s function?
The frontal lobe, especially the prefrontal cortex, plays a crucial role in higher-level cognitive functions, including executive functions like planning, decision-making, and problem-solving, as well as motor control, language, and personality.
What is the Parietal Lobe function?
Houses the somatosensory (body movement) cortex and structures involved in visual attention, as well as multisensory convergence zones.
What is the Occipital Lobe’s function?
Responsible for vision, as it is the majority of the temporal.
What is the Temporal Lobe’s function?
Involved in auditory processing, memory, and multisensory integration (convergence of vision & audition).
What is the Reticular Activating System?
The primary function of the reticular activating system (RAS) is to regulate arousal, wakefulness, and sleep-wake transitions, acting as a crucial gatekeeper for sensory information and maintaining consciousness.
Where is the Midbrain, Pons, and Medulla located at?
The midbrain is the uppermost part of the brainstem, the pons is in the middle, and the medulla oblongata is at the bottom, connecting to the spinal cord.
Located at the top-most of the brainstem, what is the midbrain’s function?
The midbrain, part of the brainstem, serves as a crucial relay center for sensory and motor information, playing a vital role in processing visual and auditory signals, regulating motor movements, and influencing arousal and alertness.
Located below the midbrain, what are the pons main function?
The pons, a region in the brainstem, plays a crucial role in relaying signals, regulating breathing, and influencing sleep-wake cycles, as well as coordinating movement and sensory functions like hearing and facial sensations.
Located below the Pons, what is the Medulla’s main function?
The medulla oblongata, or medulla, is a vital part of the brainstem that controls essential, involuntary functions like breathing, heart rate, blood pressure, and reflexes like swallowing and vomiting, connecting the brain to the spinal cord.
