|
Cardiac muscle |
Autorhythmicity & Sinoatrial (SA) node |
|
|
Autorhythmicity |
heart initiates its own heartbeat by generating electrical signals independently |
|
|
Sinoatrial (SA) node |
generates electrical signals / pacemaker |
|
|
smooth muscle |
ANS control / spindle-shape cell/ oblong nucleus/ no striations/ skill has actin and myosin/ location : blood vessels, respiratory, digestive, urinary and reproductive system. |
|
|
Nervous Tissue |
Central Nervous System (CNS) Brain & Spinal cord Peripheral Nervous system (PNS) cranial nerves, spinal nerves, & ganglia |
|
|
Nervous Tissue |
Neurons & Glial cells |
|
|
Neurons (nerve cells) |
conduct electrical signals - carry out function of nervous system/ long lived/ Do not under go mitosis |
|
|
Glial cells |
smaller and more numerous than neurons/ can undergo Mitosis/ generally support functions of neurons/ produce myelin - speeds of nerve conduction |
|
|
Neurons |
cell body (soma) / Dendrites / axon |
|
|
Cell body (soma) |
nucleus and nucleolus / RER / mitochondria |
|
|
Dendrites |
numerous, short, branching processes/ functions to receive electrical signals |
|
|
Axon |
one per cell body, usually long process/ functions to carry electrical signal away from cell body |
|
|
Skin |
Epidermis/ Dermis / Subcutaneous layer |
|
|
Epidermis |
Kerantinized stratified squamous epithelium/ keratin- strong water insoluble protein/ stratum corneum - outermost dead layer of cells |
|
|
Dermis |
papillary layer - area of dermal papillae reticular layer - dense irregular CT/ from papillary layer to subcutaneous layer/ Hair follicles, sebaceous glands, sweat glands, nerves, blood vessels |
|
|
Subcutaneous layer |
adipose tissue |
