Departmental Advising
“Smart students take advantage of resources.Successful students seek help”
Anatomy : the study of structure
Physiology : the study of function
The lab will mainly deal with AnatomyCoordinated by Dr. Corey JohnsonSelf-work with 3D models
Quizzes on blackboard BEFORE the lab
Marieb and Hoehn, third edition
Lectures are important
Grading 25% x 3 exams = 75% lab exercises = 25%
(respect your peers)No notes providedUse the ppt handouts
Answer open questions
THINK!!! Spoonfeeding- not on my watch
Blackboard
• Announcements• Syllabus, schedule• Powerpoints• Assigned readings• Links• Grades
Bookstore only (arriving Friday)
Optional Lab Manual:
Bookstore only
Recommended for those who know themselves to be kinesthetic learners. If coloring between the lines is useful to you and helps you remember lots of information, this manual is recommended. The author feels the manual is overpriced, so you will be able to “get by” without it. A more bare-bones version will be made available through blackboard at no cost.
Lab Info:• Lab is a co-requisite. Students not enrolled for a
lab will be dropped from lecture enrollment.• Labs begin Monday, August 31• A syllabus will appear on your lab blackboard site
in the next week• You will likely have an assignment due on your
first day of lab. Pay attention to the “announcements” section of you lab blackboard site.
Registration
Sign-up sheet available up front
Those with relevant needs have prioritymajor requirement – nursing, pharmacy, etc.Otherwise: Seniors > Juniors > Sophomores
Being pre- (med, dental, vet, ophthalmology, etc.) does not constitute a priority
HomeostasisPhysiology
how the varied components of living things adjust to maintain a constant
internal environment that makes possible optimal functioningWB Cannon
Homeostasis
So we have a balanced state, but it is NOT static!!
Homeostatic Imbalance = Diseases (e.g. diabetes)

Microscopic Anatomy- study of structures visible ONLY with a microscope

Different Tissues can be Found in One Organ
Epithelial Tissue
1) Covering and lining epithelium
2) Glandular epithelium
Functions1) Protection (e.g. skin)2) Sensory Reception (e.g. skin)3) Absorption (e.g. intestine)4) Secretion and Filtration (e.g. kidney)
e.g. = exempli gratia, "for the sake of an example"
Epithelial Cells are Closely Bound Together
Epithelial Cells are Closely Bound Together
Epithelial Cells are Polarized
Apical- towards the lumen/surfaceBasal- towards underlying cells
Lateral- contacting other epithelial cells
Apical
Basal
Polarized
Closely Bound Together
Avascular but Innervated
High Regenerative Capacity
Characteristics of Epithelial Cells
Classification of Epithelia
squamous cuboidal columnar
simple
stratified
Epithelial Tissue
1) Covering and lining epithelium
2) Glandular epithelium
Glandular Epithelia
Endocrine Glands: secreting internally, to the extracellular space
Exocrine Glands: secreting externally, to the body surface or body cavities
A Gland: cell/s that make and secrete products.
Endocrine Glands: secreting internally, to the extracellular space (hormones)
Exocrine Glands: secreting externally, to the body surface or body cavities
A goblet cell, secreting mucin
Modes of Secretion
