Study Notes
Nervous System
- White matter consists of myelinated axons, whereas gray matter consists of unmyelinated cell bodies and dendrites.
- White matter is found in the CNS, and gray matter is also found in the CNS.
- A functional reflex requires a sensory neuron, the thalamus, and a motor neuron.
- Stimulants increase the activity of the nervous system, while depressants decrease the activity of the nervous system.
- Motor neurons carry signals from the CNS to muscles and glands, whereas sensory neurons carry signals from sensory organs to the CNS.
- The brain stem controls basic life functions, and the diencephalon is involved in sensory relay and hormone production.
- Resting potential is the electrical charge of a neuron at rest, and action potential is the electrical signal that travels down a neuron.
- A neuron is a nerve cell, a dendrite is a branch of a neuron that receives signals, a myelin sheath is a fatty covering that insulates neurons, and a synapse is the gap between two neurons.
Endocrine System
- An organ is classified as part of the endocrine system if it secretes hormones into the circulatory system.
- The analogy is: neurotransmitters: nervous system :: hormones: endocrine system.
Muscle Types
- There are three types of muscle: Skeletal Muscle, Smooth Muscle, and Cardiac Muscle.
Integumentary System
- The first integumentary structure through which a hypodermic needle will pass is the Papillary Layer.
- Sebaceous glands are not located in the Abdominal region.
- The epidermis is composed of Keratinized stratified squamous epithelial tissue.
- The primary function of melanin is to provide protection against the sun's UV rays.
- Melanin is most important in determining skin coloration.
- Epithelial tissue is found in the lungs.
- Sebaceous glands are most active when hair is shedding.
- The integumentary system helps to regulate body temperature by retaining heat.
- Sweat and oil glands are not associated with the skin.
