Anatomy & Physiology Flashcards
(107 cards)
Types of Tissue
• Epithelial
• Connective
• Membrane
Structure of the cell
Membrane, nucleus, DNA, cytoplasm, organelles, mitochondria.
Functions of cells
Transportation: diffusion, osmosis, facilitated diffusion, active transport
Pathologies related to cells and tissues
Cancer, metastasis and scarring
Cells within the epidermis
Keratinocytes, Langerhan cells, Melanocytes, Merkle Cells
What happens in the Stratum Germinativum
Continuous cell formation, keratinocytes & melanocytes
What happens in the Stratum Spinosum & Stratum Granulosum
Cell death due to Keratinisation
What happens in the Stratum Lucidum
Only found in thick skin
Stratum Corneum
Shedding or desquamation
What’s in the Dermis Pt1
Papillary & Reticular Layers, matrix to include fibroblasts (collagen & elastin fibres) Hyaluronic Acid
What’s in the Dermis Pt2
Blood and lymph vessels, sensory nerve endings, apocrine and sebaceous glands
What’s in the Subcutaneous Layer
Adipose Tissue
Composition of the blood
Plasma, Erythrocytes, Leucocytes, Thrombocytes
Functions of the blood
Transport
Heat Regulation
Defence
Clotting
Structures of the Lymphatic System
Lymph Capillaries
Lymphatic Vessels
Lymph Nodes
Lymphatic organs and tissues
Composition of Lymph
Plasma Substances
Clear, straw coloured, fluid derived from blood plasma through capillary filtration
Functions of the Lymphatic System
Collects tissue fluid
Lymph flow is unidirectional not circular
Structure of the nervous system Pt1
Central Nervous System (brain & spinal cord)
Peripheral Nervous System
Somatic nervous system
Autonomic nervous system - sympathetic and parasympathetic
Structure of the nervous system Pt2
Neurone- motor, sensory, interneurone
Nerve pathways
Functions of the hair
Insulation
Protection
Extrinsic factors that affect
Chemical exposure, topical stimulation & damage
Intrinsic factors that affect
Genetics, nutrition, hormones, medication, disease & disorders
Different types of joint with movement
Fixed - fibrous
Semi-movable - cartilaginous
Freely-moveable - synovial joint
Range of joint movement
Flexion, extension, hyperextension, abduction, addiction, circumduction, rotation, pronation, supination.
