The endocrine system questions and answers rated A+ The endocrine system ✔✔coordinates body processes using chemical messengers called hormones Hormones ✔✔1- Control cell metabolism 2- Ke... ep the body's internal conditions stable (homeostasis) 3- Regulate growth, sexual development, and reproduction. The endocrine glands ✔✔Produce and release hormones, which are distributed throughout the body and to all our cells by the bloodstream. Hypothalamus ✔✔Is where the nervous system and endocrine system come together. It produce hormones to regulate the function of the pituitary gland. Pituitary gland ✔✔Produces various hormones to regulate many bodily functions. It is the gland that controls the endocrine system. It regulates growth and sexual maturity, and controls blood pressure and water balance in the body. Pineal gland ✔✔Small gland, attached to the brainstem, is stimulated by the levels of daylight detected by photoreceptors in the retina. It secretes melatonin Melatonin ✔✔A hormone that regulates metabolic adaptation to the night-day cycle. Thyroid gland ✔✔Secretes thyroid hormones that regulate metabolism and growth. parathyroids ✔✔Located in the thyroid gland, secrete the parathyroid hormone, which regulates calcium levels in the blood, acting on bones, kidney, and intestinal absorption of this nutrient. Adrenal gland ✔✔Secrete various hormones, such as corticosteroids and adrenaline. Corticosteroids ✔✔Regulate the cell metabolism of glucids, lipids, and proteins, as well as water balance and salt levels in the body. Adrenaline ✔✔When we sense danger or stress, this hormone increases our heart rate and blood pressure. Pancreas ✔✔Is part of the digestive and endocrine systems. Secrete two hormones for regulating blood glucose levels: insulin and glucagon Ovaries ✔✔Produce estrogens and progesterone, female sex hormones. Progesterone ✔✔Regulates the menstrual cycle and participate in pregnancy Testes ✔✔Produce testosterone, the male sex hormone. Testosterone ✔✔This hormone controls the development of male secondary sex characteristics during puberty and sperm production. Effectors ✔✔Are organs, tissues, or cells that carry out responses. Motor response ✔✔Involve movement, and muscles are the effectors of these movements. Reflexes ✔✔Are automatic, involuntary, and instantaneous responses coordinated by the nervous system. The locomotor system ✔✔Is the set of structures and organs that carry out motor responses. Types of locomotor system ✔✔The skeletal system and the muscular system The eskeletal system ✔✔Formed of bones and joints, provides support and protects internal organs. The muscular system ✔✔Formed of muscles, allows voluntary and involuntary movements. Axial skeleton ✔✔Part of the skeleton that include the vertebral column and head Appendicular skeleton ✔✔Part of the skeleton that includes the joints. Joint ✔✔Is the place where two or more bones meet. Are classified into freely movable, slightly movable, and immovable. Immovable joints ✔✔The bones that form these joints are tightly joined, allowing no degree of movement. Slightly movable joints ✔✔The bones that form these joints are separated by cartilaginous tissue. This rigid arrangement allows for limited movement. Freely movable joints ✔✔The bones that form these joints are joined by ligaments. Ligament ✔✔Highly resistant elastic tissue that binds bones together allowing a high degree of movement Bones ✔✔They are hard, resistant organs formed of cells that are surrounded by a matrix made of calcium carbonate. Have a spongy layer that accommodates the bone marrow, a tissue that produce blood cells. Cardiac muscle ✔✔Is a muscle found solely in the heart. Contracts and relaxes rhythmically, pumping blood though the circulatory system Skeletal muscle ✔✔The muscles human use to move their bones. Are attached to bones by a tissue called tendon. These are the only muscles under voluntary control. Smooth muscle ✔✔Found on the walls of the digestive tract, blood vessels, airways, and the urinary bladder, as well as in the iris. [Show More]
