Biopsychology: The Endocrine System

endocrine gland system in psychology

Think of hormones as messengers. These cells are called target cells. In hypothyroidism, reduced hormone levels cause sufferers to experience tiredness, and they often complain of feeling cold. The physicist today is no more bothered about this distinction. Also, hormones are slower to take effect, and tend to be longer lasting.

The Endocrine System

What are your thoughts on athletes and doping? The chemical signals are created and carried throughout the body using the endocrine system. Ovaries secrete estrogens and progesterone, and the testes secrete androgens, such as testosterone. The Adrenals : The adrenals are very important glands and they regulate the physiological and psychological functioning. A neurotransmitter is any specific chemical that crosses a synaptic space after being transmitted from a presynaptic cell, and acts on a post-synaptic cell. Deficient para­thyroid hormone produces muscular tenseness, and quick and intense response to stimuli.

Endocrine System

Endocrine system which is formed of all endocrine glands of body which along with nervous system of body, controls and coordinates the body functions and maintains a homestasis inside the body. In this article we have mainly emphasised the nervous and the endocrine systems. Most T4 is converted to T3 the more active form in the target tissues. Thyroid gland — The thyroid gland is critical to the healthy development and maturation of vertebrates and regulates metabolism. Its over-activity produces a giant, and its under-activity produces a dwarf. This as all about communication.

The sympathetic nervous system is involved in preparing the body for stress-related activities; the parasympathetic nervous system is associated with returning the body to routine, day-to-day operations. The Pancreas The pancreas lies in a curve between the stomach and the small intestine and controls the level of sugar in the blood by secreting insulin and glucagon. Adrenal glands — The adrenal gland is made up of two glands: the cortex and medulla. It can be further subdivided into the sympathetic and parasympathetic divisions Figure 2. Dig Deeper: Athletes and Anabolic Steroids Although it is against most laws to do so, many professional athletes and body builders use anabolic steroid drugs to improve their athletic performance and physique. Thymus Main article: The thymus gland, located in the upper thorax, declines in size and function with age. The thyroid secretes thyroxine, which is important for basic metabolic processes and growth; the adrenal glands secrete hormones involved in the stress response; the pancreas secretes hormones that regulate blood sugar levels; and the ovaries and testes produce sex hormones that regulate sexual motivation and behavior.

Adrenal Glands and the Endocrine System

The presence of this hormone restores the nervous system to relative calm. The endocrine system plays a role in regulating mood, growth and development, tissue function, metabolism, and sexual function and reproductive processes. They are chemicals that carry signals throughout the body. The efficiency of all endocrine glands seems to decrease gradually as aging occurs. Saliva is secreted by the salivary glands in response to the taste or smell of food. The somatic nervous system transmits sensory and motor signals to and from the central nervous system. Obsessive behaviors like overeating might be related to hormonal imbalances.

Endocrine System definition

The sensory information that is gathered by receptors throughout the body then passes this information on to the central nervous system. This prevents the alterations in both estrogen and progesterone concentrations that are necessary for successful ovulation and implantation. The Parathyroids : The parathyroids regulate calcium and phosphorous metabolism and are responsible for the bony structure of the body. Hint: Both systems involve chemical messengers that must interact with receptors in order to have an effect. Where are Endocrine Glands Located in the Human Body? The endocrine glands, by themselves, do not initiate any specific activity but influence and modulate the other activities. Secretes thyroxin-regulates the rate of metabolism.

The hypothalamus serves as the interface between the nervous system and the endocrine system, and it controls the secretions of the pituitary. The problem seems to be very similar to the distinction made in classical physics between matter and energy. The endocrine system gets some help from organs such as the kidney, liver, heart and gonads, which have secondary endocrine functions. Salivary glands, liver, pancreas, other digestive glands, tear glands, and sweat glands are important duct glands. In the early stages of modern psychology there was a tendency to reduce all behavioural processes to bodily processes. The endocrine system controls hormo … nes and causes puberty.

Notes on Endocrine System

This includes controlling the function of the thyroid gland and adrenal gland. Hyperthyroidism -nervousness, irritability, fatigue, fast heart beat, weight loss. Sodium ion reabsorption leads to water reabsorption, and increases in blood volume and blood pressure. The Pineal Gland The pineal gland is a pea-sized gland that apparently responds to exposure to light and regulates activity levels over the course of the day. Why would this be an effective means of contraception? Hormones are secreted directly into the blood stream by the ductless glands. For example, testosterone concentrations also influence sexual motivation and behavior in women. The adrenal glands, the thyroid glands, the pituitary gland, and the sex glands or gonads are ductless.

The other digestive glands secrete other digestive juices. Anabolic steroid use has been linked with a wide variety of potentially negative outcomes, ranging in severity from largely cosmetic acne to life threatening heart attack. Hormones act as chemical messengers, telling our body what to do and when to do it. For example, if the thyroid gland has secreted the right amount of thyroid hormones into the blood, the pituitary gland senses the normal levels of thyroid hormone in the bloodstream. The former has great influence on the growth of bones. Similarly, male mice or rhesus monkeys that lose a fight decrease circulating testosterone concentrations for several days or even weeks afterward. In females, the ovaries release oestrogen which controls the regulation of the female reproductive system, including the menstrual cycle and pregnancy.
