animal cells and tissues

Muscle tissues produce movement via?

contractions

Muscle cells

Myocytes

Myocytes are filled with what filaments?

1. Actin

2. Myosin

What type of force do muscle tissues exert, which causes movement

Mechanical force

3 types of muscle tissues

1. Skeletal

2. Smooth

3. Cardiac

Muscles that are striated and contain more than one nucleus per cell

Skeletal muscles

Multi-nucleated state of muscle cells

Syncytium

Most skeletal muscles are attached to boned via a strong and elastic specialized connective tissue called?

Tendons

Skeletal muscle

Where are the nucleus located at the striated muscle cells

Periphery

Striations are composed of two bands

1. I-bands

2. A-bands

no striations, involuntary

Smooth muscle

How many nucleus per cell in smooth muscles

(1)

most often arranged in sheets in the wall of organs like stomach, intestines, and uterus

smooth muscles

where is the nuclus located at in the smooth muslce

centrally

striated muscles found only in vertebrate hearts

Cardiac muscles

How many nucleus in cardiac muscles

1-2

Branching cardiac muscle cells are are connected via

intercalated discs

Help synchronize the contraction of the muscle cells

Intercalated disc

What regulates the contraction of the heart

1. Hormones

2. Automatic nervous system

function in the animal body by facilitating communication, coordination, and control

Nervous tissues

small, string- like structure that carries impulses across the body

Nerve

outer loose connective tissue covering of the nerve

epineurium

Nerve is composed of:

1. Epineurium

2. Nerve bundles/ fascicles

Nerve bundles

Fascicles

Fascicle’s dense sheet of connective tissue

perineurium

Fascicle is composed of bundles of:

axons/ nerve fibers

Layer of white insulating material

Schwann sheath/ Myelin sheath

Wraps around each nerve fiber and appears to fill int he rest of the fascicle’s interior

Endoneurium

Functional unit of the nervous system

Neuron

Neuron is composed of?

1. Cell body/ soma

2. Protoplasmic extensions

The neuron’s cell body contains?

Nucleus

Protoplasmic extensions of the neuron

1. Dendrites

2. Axons

Branch-like protoplasmic extension

Dendrites

Longer, thin protoplasmic extension of the neuron

Axons
