Nerves

...  spinal cord through muscles that you control consciously, these are called voluntary or skeletal muscles. It also has receptors in the skin that detect information inside and around the body. The autonomic nervous system is the one responsible for connecting the brain stem and spinal cord with the internal organs. This part regulates the processes in our body that does not require any  ...

Parasympathetic Division

...  parasympathetic division is one of the divisions of the autonomic nervous system that is concerned with digestion, urination and defecation. It has a different effect from that of the sympathetic division because this division involves the body in a state of rest. Unlike the sympathetic, the parasympathetic decreases respiration and heart rate; hence, it conserves and stores energy instead of  ...

Neurotransmitters

...  and spinal cord and is rapidly metabolized and recycled. This catecholamine has an excitatory or inhibitory effect in the body. Dopamine This substance has an excitatory effect and is found in the autonomic nervous system or ANS. Oversecretion of this substance results to schizophrenia. All of these neurotransmitters have the purpose of transmitting neural reactions from the neurons to the  ...

Sympathetic Division

...  This is what is called the “fight or flight” response of the sympathetic division of the body to emergency situations. What is the sympathetic division? This is a division of the autonomic nervous system that is responsible for preparing the body to fight or flight. The body does this by initiating the occurrence of a series of processes. These various processes help the body  ...

Abducens Nerve

...  nervous system is divided into two parts: the central nervous system and the peripheral nervous system. The peripheral nervous system is further subdivided into the autonomic nervous system and the sensory-somatic nervous system. The sensory-somatic system consists of 12 pairs of cranial nerves and 31 pairs of spinal nerves. The sixth pair among these 12 pairs is the abducens nerves. Anatomy  ...

Pineal Gland

...  innervated by the autonomic nervous system, and only that. Even if the pineal gland is located in the brain, it does not receive innervation from the brain. The superior cervical ganglion of the autonomic nervous system is specifically in charge of this innervation. The pineal gland exists in most mammals, and its function is explicitly recognized in some organisms. But, that does not  ...
