A. Sponges
They are multicellular organisms that have bodies full of pores and channels allowing water to circulate through them, consisting of jelly-like Mesohly sandwiched between two thin layers of cells. Sponges have unspecialized cells that can transform into other types and that often migrate between the main cell layers and the mesohly in the process. Sponges do not have nervous, digestive or circulatory systems. Instead, most rely on maintaining a constant water flow through their bodies to obtain food and oxygen and to remove wastes.

Axons of the nervous system are described as afferent and efferent according to the direction in which they carry information. W
Ahat [919]

Answer:

The correct option is b) motor output of the spinal cord

Explanation:

Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.

The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.

Ears

¿Qué es el oído y qué hace?

El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.

El oído externo

El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.

El oído medio

El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.
