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.
