Anatomical Knowledge Flashcards
What is the function of the gracile nucleus
LOCATION/INPUT/OUTPUT/ORGANIZATION
What: Major sensory pathway responsible for transmitting fine touch, proprioception
Where: Medulla Oblongata
Input: Sensory input from proprioceptors, mechanoreceptors, and tactile receptors
Output: Brainstem and higher brain regions
SOMATOTOPICAL ORGANIZATION
What is the function of the nucleus of the solitary tract
Where: Medulla Oblongata
Input: proprioceptors, mechanoreceptors, and tactile receptors located throughout the lower half of the body
Ouput: Brainstem and other brain regions
what: visceral function (baroreceptor etc)
What is the function of the secondary motor area
Where: frontal lobe
What: planning and execution of voluntary motor movements, sequencing of movements, especially those that require more complex, coordinated actions.
Input: M1, basal ganglia, cb, thalamus, premotor cortex,
Output: spinal cord, cerebellum premotor cortex, basal ganglia et thalamus.
What is the function of the VISa
does contribute to visual processing, particularly in the context of spatial perception and visual attention
What is the function of the superior colliculi
Integration of multisensory information,help translate visual information into motor commands, facilitating the execution of appropriate motor responses
What is the function of the pontine reticular nucleus
Cortico-Pontine-Cerebellar Pathway, balance and posture.
What is the function of the Midbrain reticular nucleus
Attention, motor control, pain pathway
What is the function of the retrosplenial area
Cingulate cortex
helps individuals navigate their surroundings, form spatial and episodic memories, and integrate visual and spatial information to create a coherent representation of the environment
What is the function of the anterior cingulate area
daptive behavior, decision-making, emotional regulation, and overall cognitive control.
What is the function of the caudoputamen
motor control, cognition, reward processing, and emotional regulation.
What is the function of the gigantocellular reticular nucleus
in reticular formation
Involved in motor control, respiration, autonomic function, pain modulation.
What is the function of the magnocellular reticular nucleus
Plays a role in motor control, particularly in fine motor coordination. It receives input from various sources and contributes to voluntary motor movements, especially those involving the upper limbs
What is the function of the Red nucleus
Gait, posture, muscle tone
What is the function of the periaqueductal gray
Pain modulation, autonomic function, emotionnal response…
What is the function of the zona incerta
Integrative region, sensory and motor aspects.
