Simple squamous epithelium
o Simple layer of flat cells
o Filtration, diffusion, and secretion
o Lines vessels (endothelium), forms serous membranes (mesothelium), in
air sacs of lungs, Bowmans capsule in kidneys, surface of tympanic
The spinal cords gray matter is the site for integration of EPSPs and IPSPs graded potentials; the
white matter contains sensory tracts and motor tracts- highways where sensory input goes to
brain and motor output goes to effectors.
1. Describe the protec
Anatomy of autonomic motor pathways:
Unlike somatic nervous system, autonomic nervous system has two motor neurons.
For both sympathetic and parasympathetic nervous system of the ANS, the first of the
two motor neurons = preganglionic neuron; it
1. Identify the major structures and functions of the nervous system in the maintenance of
o 12 pairs emerge from the brain
o bundle of many axons and their associated connective tissue and blood vesse
1. Identify the principal parts of the brain, and describe how the brain is protected.
principal parts of the brain
continuous with the spinal cord
consists of medulla oblongata, pons, and midbrain
posterior to brain stem
Stored in synaptic vesicles and released by exocytosis, diffuses across synaptic cleft and
binds to receptors on postsynaptic plasma membrane
Two types of cholinergic receptors: nicotinic and muscarinic receptors- both binds to
27 | FLUID, ELECTROLYTE AND ACID-BASE HOMEOSTASIS
1. Compare the location of ICF and ECF, and describe the various
fluid compartments of the body.
- Body fluids are present into 2 compartments: inside cells
(ICF/cytosol) and outside cells (ECF)
- Most of
25 | Metabolism and Nutrition
1. Define the term metabolism, and explain the role of ATP in
anabolism and catabolism.
- Metabolism refers to all the chemical reactions that occur in the
body (catabolism + anabolism)
- Catabolism are chemical r
1. Describe the functions of blood.
Most body cells cannot move to get what they need or eliminate what they dont need, instead,
needs are met by two fluids: blood and interstitial fluid. Blood is liquid connective tissue;
interstitial fluid is the fluid
20| The Cardiovascular System: The Heart
1. Describe the location of the heart.
The heart located in the mediastinum (sternum->vertebral column, first
rib->diaphragm, between lungs), about 2/3s of it is to the left of the
Imagine the heart as a co
