Axons from the peripheral sensory organs, or intermediate nuclei, synapse in the thalamus, and thalamic neurons project directly to the cerebrum.
It is a requisite synapse in any sensory pathway, except for olfaction.
The thalamus does not just pass the information on, it also processes that information.
Which special sense does not travel through the thalamus?
The sense that does not go through the thalamus is smell. Smell is detected by chemoreceptors in the olfactory epithelium in the nose.
What part of the motor pathway inhibits inappropriate movements?
What part of the motor pathway inhibits inappropriate movements? Motor learning occurs in the substantia nigra of the basal nuclei.
What should not cross the blood brain barrier with ease?
Large molecules do not pass through the BBB easily. Low lipid (fat) soluble molecules do not penetrate into the brain. However, lipid soluble molecules, such as barbituate drugs, rapidly cross through into the brain. Molecules that have a high electrical charge are slowed.
Which brain nucleus serves as the body’s master clock?
Does taste go through thalamus?
Does taste pass through thalamus? Smell is the only sense that doesn’t pass through the thalamus, taste involves signals moving from the tongue to the ventral posteromedial thalamic nuclei , and the thalamus.
Does hearing go through the thalamus?
Primary Auditory PathwayThis pathway carries messages from the cochlea to a sensory area of the temporal lobe called the auditory cortex. The last neuron of the primary auditory pathway connects the thalamus with the auditory cortex. At this stage the message has already been largely decoded.
What is the boss of the autonomic nervous system?
The hypothalamus functions in: regulating the autonomic nervous system.
Which is a type of tonic receptor that detects both continuous deep pressure and distortion of the skin?
Pacinian corpuscles; a large, encapsulated tactile receptor that detects deep pressure and high-frequency vibration. An encapsulated tactile receptor that detects both continuous deep pressure and distortion in the skin; they do not exhibit adaptation.
What part of the spinal cord carries motor information from the brain?
Spinal Cord Nerve BranchesThe posterior root is the sensory (afferent) root that carries sensory information to the brain from other areas of the body. The anterior root is the motor (efferent) root that carries motor information to the body from the brain.
