Proprioception and Sensory Receptors

Front

What is a muscle spindle?

Back

A muscle spindle is a sensory receptor located within a muscle that detects changes in the muscle's length, acting as a 'stretch detector,' and sends information about muscle stretch to the central nervous system, contributing to proprioception.

What is the function of a Golgi tendon organ (GTO)?

Back

A Golgi tendon organ is a sensory receptor located at the junction of a muscle and its tendon, which detects muscle tension and sends signals to the nervous system about the force being exerted by that muscle, acting as a protective mechanism to prevent excessive muscle contraction and potential injury.

What is proprioception?

Back

Proprioception is the body's ability to sense its own position and movement in space, allowing you to know where your body parts are without relying solely on vision. It's crucial for balance and coordinated movement.

Front

What is a cribriform plate?

Back

The cribriform plate is a bone in the skull that separates the nasal cavity from the brain. It's part of the ethmoid bone, and it's located at the base of the skull.

Front

What are olfactory formina?

Back

Olfactory foramina are small holes located in the cribriform plate of the ethmoid bone, which form the roof of the nasal cavity, allowing the olfactory nerve fibers (responsible for the sense of smell) to pass through from the nasal cavity to the olfactory bulb in the brain; essentially, they are the openings that enable our sense of smell.

Front

what are olfactory neurons

Back

Olfactory neurons, also known as olfactory sensory neurons (OSNs), are nerve cells that detect and send information about odors to the brain. They are located in the nasal epithelium, which lines the upper part of the nose

Front

What is the only type of neuron that can be replaced?

Back

Olfactory neurons

Front

What is required of a substance for us to be abe to smell it?

Back

I substance must be airborne. That means part of it must evaporate into vapor aka it must be volatile.

Front

What is the gustatory sense?

Back

The gustatory sense, also known as taste, is the ability to perceive the flavors of substances in the mouth. It's a vital sense that helps us determine if food is safe to eat and provides the nutrients our bodies need.

Front

what are papillae

Back

Papillae are the little bumps on the top of your tongue that help grip food while your teeth are chewing. They also have another special job — they contain your taste buds, the things that help you taste everything from sour lemons to sweet peaches.
