Diencephalon, basal ganglia and cerebral cortex

Can you label where the uncus is located?

Where is the diencephalon located and what does it consist of?

Thalamus, hypothalamus, Epithalamus (Habenula and pineal body and subthalamus

What joins the two sides of thalamus together?

Interthalamic adhesion

What is the dark purple section of the right thalamus?

medial geniculate nucleus, relays to the primary auditory cortex

What is the dark blue section?

lateral geniculate nucleus, relays to the primary visual cortex,

Which section relays to the primary gustatory cortex?

ventral posteromedial

Can you label the rest of the structure of the thalamus

What is the function of the thalamus?

Sensory relay

Support for motor systems

Mental operation regulation

Which pathway is a sensory pathway that relays pain , tempreature and crude touch? described as a reactive pathway?

Spinothalamic pathway

Which sensory pathway is described as descriminative and relays seosory information from proprioception, fine touch and vibration?

Dorsal column-medial lemniscus pathway

Can you label the structure the yellow arrow is pointing to?

Mammillary body

Can you label the nucleus of the hypothalamus?

can you label the basal ganglia?

What aspect of the basal ganglia is this image taken from?

Sagittal

What is the red, green and dark blue section in this image

What is the pink and yellow section in this image?

Can you label all the green arrows on this image?

Can you label this parasagittal veiw of the brain?

Can you label this coronal section of the brain?

There are three types of cerebral white matter fibres, can you name each category?

Association fibres

Commissural fibres

Projection fibres

What is the voluntary motor pathway that controls the head and neck?

Corticonuclear (corticobulbar) pathway

What is the voluntary motor pathway that controls the skeletal muscles below the head?

Corticospinal (pyramidal) pathway

Can you describe the direct pathway for voluntary movement?

Direct pathway → Facilitates movement by Disinhibition

Cortex excites the striatum → striatum inhibits the globus pallidus internus → Globus pallidus internus is inhibited so the thalamus is disinhibited → thalamus excites the motor cortex → signal passes to the spine → voluntary movement

Can you explain the indirect pathway of voluntary movement?

Indirect → Inhibition of unwanted movements

Cortex excites the striatum → Striatum inhibits the globus pallidus externus → Globus pallidus externus inhibits subthalamic nucleus → inhibited subthalamic nucleus excites the globuspallidus externus → GPE. inhibits thalamus → Motor cortex inhibited → spine → stops movement

Can you label the cingulate sulcus, singulate gyrus, uncus and parahippocampal gyrus

Can you label the limbic lobe?

What is the green arrow pointing to?

Hippocampus

What are tyhe structure sof the limbic system?

Cingulate cortex

Septal area

hypothalamus

hippocampus

amygdala

What is the function of the limbic system?

Controls visceral functions throught he autonomic nervous system and the endocrine system and is involved in emotions and memory reproduction and nutrition

which number is brocas area?

45/44
