Endocrine system

the body’s “slow” chemical communication system; a set of glands that secrete hormones into the bloodstream.

Hormone

chemical messengers that are manufactured by the endocrine glands travel through the bloodstream and affect other tissues.

Pituitary gland

the endocrine system’s most influential gland. Under the influence of the hypothalamus, the pituitary regulates growth and controls other endocrine glands.

Thyroid

Makes and releases certain hormones.

Adrenaline

increases heart rate, blood pressure, and blood sugar, providing us with a surge of energy, known as the fight-or-flight response.

Estrogen

responsible for the development and regulation of the female reproductive system and secondary sex characteristics

Testosterone

plays a key role in the development of male reproductive tissues such as testicles and prostate, as well as promoting secondary sexual characteristics such as increased muscle and bone mass, and the growth of body hair

Pancreas

Your___ helps with digestion and releases hormones that regulate your blood sugar.

Testes

Secretes male sex hormones

Ovaries

Secretes female sex hormones

Nervous system

the body’s speedy, electrochemical communication network, consisting of all the nerve cells of the peripheral and central nervous systems.

Central nervous system

the brain and spinal cord.

Peripheral nervous system

the sensory and motor neurons that connect the central nervous system (CNS) to the rest of the body.

Autonomic nervous system

the part of the peripheral nervous system that controls the glands and the muscles of the internal organs (such as the heart). Its sympathetic division arouses; its parasympathetic division calms.

Somatic nervous system

the division of the peripheral nervous system that controls the body’s skeletal muscles. Also called the skeletal nervous system.

Sympathetic nervous system

the division of the autonomic nervous system that arouses the body, mobilizing its energy in stressful situations.

Parasympathetic nervous system

the division of the autonomic nervous system that calms the body, conserving its energy.

Sensory neurons

neurons that carry incoming information from the sensory receptors to the brain and spinal cord.

Motor neurons

neurons that carry outgoing information from the brain and spinal cord to the muscles and glands.

Interneurons

neurons within the brain and spinal cord that communicate internally and intervene between the sensory inputs and motor outputs.

Reflex Arc

a neural pathway that allows for an involuntary, rapid response to a stimulus (?) 

Neural network

The name of the brain’s neurons clusters when in work groups (this description sucks im sorry)
