The thyroid gland is a vital butterfly-shaped endocrine gland situated in the lower part of the neck. It is present in front

The pituitary gland or the hypophysis cerebri is a vital structure of the human body as it performs essential functions

The Pituitary Gland/The pituitary endocrine gland, which is located in the bony sella turcica, is attached to the base of

Hormones are released into the bloodstream through which they travel to target sites. … Water-soluble hormones bind to a receptor protein on the

The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction,

Neurotransmitters and Receptors/Neurotransmitters are chemical messengers that transmit a signal from a neuron across the synapse to a target cell, which can be a different

Functions of the Autonomic Nervous System/The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral nervous system that

Structure and Functions of the Autonomic Nervous System/The autonomic nervous system (ANS), formerly the vegetative nervous system, is a division of the peripheral

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate,

Hearing allows one to identify and recognize objects in the world based on the sound they produce, and hearing makes communication

Pain Sensation/Pain is a general term that describes uncomfortable sensations in the body. It stems from the activation of the

A reflex arc is a neural pathway that controls a reflex. Invertebrates, most sensory neurons do not pass directly into the brain, but synapse in the spinal cord. This allows for

Sensory and Motor Pathways/Generally, spinal nerves contain afferent axons from sensory receptors in the periphery, such as from the skin,

The descending tracts are the pathways by which motor signals are sent from the brain to lower motor neurones. The lower motor

Motor pathways carry signals from the brain to skeletal muscle and smooth muscle such as those contained in glands. The system consists of upper and lower motor

Gross motor (physical) skills are those which require whole-body movement and which involve the large (core stabilizing) muscles of the

A motor skill is a learned ability to cause a predetermined movement outcome with maximum certainty. Motor learning is the relatively permanent

The motor activity involves movement quality and quantity that both influence and are influenced by states of arousal. Imbedded in activity levels are

Distribution of Spinal Nerves means the branch is where the start to the end of the nerve and connect to
