Pituitary Gland – Anatomy, Types, Funtions
The pituitary gland or the hypophysis cerebri is a vital structure of the human body as it performs essential functions for sustaining life. It has the pseudonym of “the master gland.” The location of the gland is within the sella Read More …
The Pituitary Gland – Anatomy, Structure, Functions
The Pituitary Gland/The pituitary endocrine gland, which is located in the bony sella turcica, is attached to the base of the brain and has a unique connection with the hypothalamus. The pituitary gland consists of two anatomically and functionally distinct Read More …
Hormone Secretion – Anatomy, Types, Functions
Hormone Secretion/Hormones are secreted from the glands of the endocrine system, they are specific in that each hormone causes a response in a specific target organ or group of cells, rather than on the body as a whole. Exocrine hormones are secreted via a duct into the blood Read More …
Hormone Interactions – Anatomy, Types, Functions
Hormone Interactions/Hormones are chemical messengers that interact with receptors present on the surface of a cell membrane or with receptors that are located inside the cell, in the cytoplasm (cytoplasmic receptors). This interaction gives rise to the effects hormones exert Read More …
Mechanisms of Hormone Action – All About You Can Know
Mechanisms of Hormone Action/Hormones are the messenger molecules of the endocrine system. Endocrine hormones travel throughout the body in the blood. However, each hormone affects only certain cells, called target cells. A target cell is the type of cell on which a hormone Read More …
Hormone Action – Mechanisms of Hormone Action
Hormones are released into the bloodstream through which they travel to target sites. … Water-soluble hormones bind to a receptor protein on the plasma membrane of the cell. Receptor stimulation results in a change in cell activity, which may send feedback to the Read More …
Endocrine System – Anatomy, Types, Functions
The endocrine system is the collection of glands that produce hormones that regulate metabolism, growth and development, tissue function, sexual function, reproduction, sleep, and mood, among other things. The endocrine system is a messenger system comprising feedback loops of the hormones released by internal glands of an organism directly into Read More …
Neurotransmitters and Receptors
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 neuron, muscle cell, or gland cell. Neurotransmitters are chemical substances made by the neuron specifically to transmit a message.[rx] Neurotransmitters are released from synaptic vesicles in synapses into Read More …
Functions of the Autonomic Nervous System
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 supplies smooth muscle and glands, and thus influences the function of internal organs.[rx] The autonomic nervous system is a control system that Read More …
Structure and Functions of the Autonomic Nervous System
Structure and 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 supplies smooth muscle and glands, and thus influences the function of internal organs.[rx] The autonomic nervous system is a control Read More …
Autonomic Pharmacology – Drugs Work on Autonomic Nervous System
Autonomic Pharmacology/The basis of autonomic pharmacology reflects the physiology of the sympathetic nervous system (SNS) and the parasympathetic nervous system (PSNS) to regulate involuntary reactions to stresses on multiorgan systems within the body. When a pathologic process is present that Read More …
