Week 3 Flashcards
Nervous Control, Parts of the Brain, Neurons, Endocrine System
What is the role and function of the nervous system?
Control and coordinate the functioning of the body. Receive information from the sensory neuron, process information by the brain and spinal cord and respond by an effector (muscle/gland)
What is the sensory receptor of the ear?
Mechanoreceptors
What is the sensory receptor of the eye?
Photoreceptors
What is the sensory receptor of the nose?
Chemoreceptors
What is the sensory receptor of the tongue?
Chemoreceptors
What is the sensory receptor of the skin?
Thermoreceptors Mechanoreceptors Pain Receptors
What are the stimuli of the ear?
Sound
What are the stimuli of the eye?
Light
What are the stimuli of the tongue?
chemicals
What are the stimuli of the nose?
chemicals
What are the stimuli of the skin?
temperature, touch, movement, pain
What is the central nervous system (CNS)?
Control center of the body that processes incoming messages from the environment.
What parts of the body relate to the CNS?
Brain and spinal cord
What is the peripheral nervous system (PNS)?
Carries information to and from the central nervous system to the rest of the body.
Has somatic and autonomous
What is the somatic nervous system?
controls voluntary skeletal movements
What is the autonomous nervous system?
controls involuntary actions, which occur without conscious control.
Has sympathetic and parasympathetic
What does sympathetic mean in the nervous system?
Fight, flight or freeze in the body
What does parasympathetic mean in the nervous system?
rest and digest. conserve and restore
What is the reflex arc?
an involuntary and instantaneous movement in response to a stimulus.
What does the sensory neuron do?
carry messages from receptors to spinal cord.
What does the interneuron do?
Interneuron sends two messages: one to the brain and one to the muscles via a motor neuron
What is the cerebrum and what are the 4 labels it’s divided into?
Associated with higher thinking orders.
Frontal lobe
Parietal lobe
Temporal lobe
Occipital lobe
