and in the sea. Once submerged‚ it has been observed that even infants show this reflex. To test whether or not adult humans have this reflex test subjects were used to compare findings based on specific variables. Marine mammals are an excellent example of this due to the fact they have to dive to extreme depths in order to get food. Introduction: Marine mammals such as seals‚ whales‚ and dolphins exhibit a reflex that allows for them to dive for extended periods of time. This adaptation allows

signals synapse with interneurons‚ which in turn transmit impulses to motor neurons and into the effector organs (Ocampo and Reyes). An organism can response to a certain stimuli even if its brain is damaged or slightly destroyed through the spinal cord reflex. This shows that even if the toad( Bufo marinus)was decerebrated (only the brain was destroyed or damaged )‚ it can withdraw its limbs as the effect of acetic acid ‚ maintain its proper posture ‚ croak and swim because the spinal cord is still intact

It permits movement of the body‚ maintains posture‚ and circulates blood throughout the body Muscles provide strength‚ balance‚ movement and heat for the body to keep warm There are three distinct types of muscles: skeletal muscles‚ cardiac or heart muscles‚ and smooth (non-striated) muscles Skeletal muscle is a form of striated muscle tissue existing throughout the human body‚ and which

Spinal nerve(twelve pairs) which are in the spinal cord. 2. Define the terms reflex and spinal reflex and identify the components of a reflex arc. A reflex is an automatic response to a stimulus produced by a reflex arc. It occurs without conscious thought. Reflexes are homeostatic. A spinal reflex is any reflex action mediated through the center of the spinal cord. A reflex arc is the nerve pathway involved in a reflex action including at its simplest a sensory nerve and a motor nerve with a synapse
