Week 9 - Chapter 16 Somatic Sensation

________ is the conscious or subconscious awareness of changes in the external or internal environment.

Sensation

________ is the conscious awareness and interpretation of sensations, primarily a function of the cerebral cortex.

Perception

How does the type of sensation and the reaction vary?

Varies depending on where sensory impulses are sent in the CNS.

A ________ is a type of sensation, and usually, each sensory neuron serves only one modality

Sensory modality

General senses include:

Somatic (touch, pressure, vibration, warmth, cold, pain, itch, tickle, proprioception) and visceral senses

Special senses include:

Smell, taste, vision, hearing, and equilibrium

What four events must occur for a sensation to arise?

Stimulation, transduction, generation of impulses, and integration

______ receptors are associated with general senses (like free nerve endings)

Simple

_______ receptors are associated with special senses (like the eyes and ears)

Complex

How do sensory receptors respond to stimuli?

By producing receptor potentials

What is adaptation in sensory receptors?

Adaptation is the decrease in sensitivity during a long-lasting stimulus. Receptors can be rapidly or slowly adapting.

Somatic sensations include:

Tactile sensations (touch, pressure, vibration, itch, tickle), thermal sensations (warmth, cold), pain, and proprioception

Where are receptors for tactile, thermal, and pain sensations located?

In the skin, subcutaneous tissue, and mucous membranes of the mouth, vagina, and anus

What types of receptors detect touch?

Tactile corpuscles of touch (rapidly adapting) and hair root plexuses, and slowly adapting nonencapsulated sensory corpuscles

What types of receptors detect pressure?

Nonencapsulated sensory corpuscles and lamellar corpuscles

What types of receptors detect vibration?

Tactile corpuscles and lamellar corpuscles

What types of receptors detect itch, tickle, and temperature?

Free nerve endings (itch, tickle, thermoreceptors)

Where are cold and warm receptors located?

Cold receptors are in the stratum basale of the epidermis; warm receptors are in the dermis

_______ receptors (free nerve endings) are found in nearly every body tissue.

Pain

Fast pain is carried by ____ fibers (medium diameter, myelinated)

A

Slow pain is carried by ___ fibers (small diameter, unmyelinated).

C

Where are proprioceptors located?

In muscles, tendons, joints, and the inner ear

What are the types of neurons involved in somatic sensory pathways?

First-order, second-order, and third-order neurons

Where do somatic sensory neurons send signals besides the cerebral cortex?

The cerebellum and reticular formation of the brainstem.

What pathway carries touch, pressure, vibration, and proprioception signals?

The posterior column–medial lemniscus pathway

What pathway carries pain, temperature, touch, and pressure signals?

The anterolateral pathway

Sensations from the face, nasal cavity, and oral cavity are transmitted through the _______

Through the trigeminothalamic pathway

Where do somatic sensory inputs from different body parts go in the brain?

They are received by specific regions of the primary somatosensory cortex (postcentral gyrus) in the cerebrum

What pathways transmit nerve impulses to the cerebellum for posture and coordination?

The anterior and posterior spinocerebellar tracts

Lower motor neurons are:

Motor neurons that control movement and are the final common pathway for movement control

What four neural circuits provide input to lower motor neurons?

Local circuit neurons, upper motor neurons, basal nuclei neurons, and cerebellar neurons

What is the primary motor cortex?

The precentral gyrus of the brain, which is the major control region for voluntary movements

What pathways do upper motor neurons use to send signals to lower motor neurons?

Direct pathways (corticospinal and corticobulbar pathways) and indirect pathways (rubrospinal, tectospinal, vestibulospinal, reticulospinal tracts)

What is the role of the corticospinal pathways?

They convey nerve impulses from the motor cortex to skeletal muscles in the limbs and trunk

What do the corticobulbar pathways control?

Skeletal muscles in the head

What does the cerebellum do in movement control?

It helps with learning and performing rapid, coordinated, highly skilled movements, and maintaining balance and posture

What two systems control sleep and wakefulness?

The suprachiasmatic nucleus and the reticular activating system

How many stages are there in non-rapid eye movement sleep?

Four stages

What is a coma?

A state of unconsciousness where an individual has little or no response to stimuli

What is memory?

The process of storing and retrieving information learned
